I could say what idiots but that not going to help. All they had to do initially to drill mounting holes in correct positions; although, the ZT730 series is a replacement for the SV730 and the mounting holes should had lined up properly as both had the same 10" bolt circle. But doesn't mean the holes are in the same place on the circle. And even now they can drill out and Heli coil the mounting holes. Something you couldn't easily do on the SV. And they should be using serrate flange head torqued to spec not just hand tighten.
Both the SV and ZT uses 3/8 self tappers. The problem is the ZT has less meat persay for threads. It recommend that you Heli coil back to 3/8-16 threads approximately 1 inch deep provided they are not too mess or if there is enough material left at the mounting go to M10 x 25. Either way the Heli coil tap would need to be a bottoming tap which is not part most kits but as a separate tap. And it not cheap. I know as I got a 3/8-16 Heli coil bottom tap inbound here that was $41 plus shipping. Now max hole size is 25/64 for the 3/8-16 and 13/32 for M10-1.25(fine thread) or 10.5mm for M10-1.5 (course thread). As said it depends how much material is left to work with.

It appears the original engine was a SV730-0023 superseded to ZT730-3023 but that engine is NLA now.

Well, IF Tiger actually did his research he would know that is impossible. I actually called my RBI Kohler Tech support to verify these are not thru holes and the size of the screws used in the holes initially which were 3/8-16 self tappers. Actually I was mainly checking on the screw as the SV had 8.5mm holes and the KT has 9mm holes which means less material for the self tappers to bite into for threads. Otherwords the screws if over tighten can pull out easier.
Personally I think it going very difficult to use thru screws since would require drilling thru holes and then mounting the sump/oil pan/closure plate and reassemble the engine while this is attached to the mower's engine plate.
I wish posters would stop just throwing things out just to hear their head rattle or in this case the keys rattle.
Here is the location of the mounting screw holes.

An expensive lesson learned. 
If the clowns at the John Deere dealership ever gets this straightened out, fire them and find a competent repair shop.

This would have eliminated the problem of him being wrong.
-I wish- there weren't so many people on social media and in forums that are just chomping at the bit to pull the
"GOTCHA" to tell someone they're wrong.
It's actually worse than the grammar Nazis because nobody pays any attention to them at this point and we all just wish they'd go away and lose their internet connections.
The pedantic nature of it becomes quite intense!
Why in the world would anyone waste so much time and effort looking things up or calling a representative etc when it's not their problem.
This is just a casual discussion forum where we offer advice that we think may help and we share experiences when we've actually done the exact repair or procedure etc so we can save them some time and let them know what will work and what won't or what is likely not to.
It's not our responsibility to delve into something that we haven't actually done to find out more information for ourselves so we can pass along to someone else.
It'd be just as simple to recommend they do that instead of someone else doing it since - it is their situation.
It's not that I don't want to be helpful but having to be concerned that someone's going to jump your crap and criticize a suggestion makes it almost not worth posting.
Almost I said because I thrive on conflict and have no problem stirring the pooh-poo pot.
His suggestion of using longer bolts and a nut on top (I would have probably added a lock washer too in the recommendation or at least a special type of locking nut) was still a valid suggestion since it works on a large majority of engines on at least some of their mounting legs.
I have learned in the past 3 or 4 years especially with facebook, to always word my post so they are not so specific that anyone has any grammatical standing to criticize my posts.
This leaves them only to criticize my opinions and personal preferences and do the character assassinations, which they certainly and quickly do.
I just love picturing their head spinning around and frothing at the mouth because they think I'm such a terrible human being because they can't
educate me, show me the light, help me become aware, get me to understand.... and it usually takes 2-3 times before they will give up and tell me what they really think of me personally - All most commonly from only one comment.
It's absolutely hilarious but it does make me hate most people.
Hate might be a strong word all the time, but it certainly applies a lot of the time and for many of them.
It's not that I'm sensitive, a snowflake or get been out of shape about it, but I have to admit it didn't use to bother me BECAUSE I didn't know about it.
But we have done, and the powers that be, is continually keep people interacting and at each other's throats by always giving them two different sides at minimum to choose.
Oh well, I don't think much of the world anyways. So there's that too.

What he should have said was IF there's room to drill through and put a nut on top. Lol

It is not your responsibility to research or even bother considering what model number it is if you don't know exactly how that engine looks off the top of your head before you give advice or recommend something that they may consider that might work.
See all those special words I use like may and might??
I find you have to do this today because certain people are always out there looking to criticize others when the intent, like yours was 100% positive.
I would rather have people brainstorm and throw all kinds of suggestions out there and the person can read through and decide which ones they want to further look into.
A few times that people being critical and you scroll on by and don't even bother to give the suggestion because it's not worth your time to do any research on it because it's not your problem and you don't want to say something that somebody else might claim you don't know what you're talking about.
Don't need to know what you're talking about because you don't have that engine in front of you and it's not your project.

Absolutely! I just wrote another big one about this because it brushed me the wrong way too.

It's not our responsibility.
This is why I make all my suggestions with certain keywords that let me off the hook.
Saying things like "depending on the mounting design, you may be able to...."
Allows me to make a suggestion and reference what I have done many times on other engines (possibly with different designs) without being factually inaccurate.
Now, I don't like it when people make overly generalized statements as fact because it can't be accurate if it's not 100% accurate if there's even one outlier.
This is why you say things like most or the majority of...
There's just certain ways how the language works and one little word can make all the difference between being accurate and inaccurate even if the odds are highly against it working or even being possible.

A few years ago, I needed the engine info on my Gravely 260Z. No serial numbers on old engine. I wrote to Gravely and asked if they might be able to tell me the engine. They wrote back and gave me what the mower came with. (Boooyahhh)
I then ordered the current replacement engine. The new engine was in fact a direct replacement and went in like a charm. Was very impressed with the whole experience and I use that same mower today..

Even if the companies do technically have the information -somewhere- the likelihood of speaking to a person who can find that information is very small.
So, in my experience, it is the hard way and slow way to do it and most of the time an exercise and futility because they can't help you at all.
What I have found is far more quick and convenient and just as accurate lol, is to do a Google search for what you're looking for or even just do a search and click on images and then find the ones that look just like yours.
Use within just a few clicks I can find one with some type of description or someone talking about the brand and model of engine on one that looks just like mine so then I can take that newly found information and typically do a second search with that to further clarify and confirm with better pictures etc to make sure it is the compatible engine for what I need.
I've just heard too many people do a needle in a haystack kind of approach dealing with manufacturers and these companies are very poorly designed to offer any type of actual experienced people with Hands-On information or technical or even common failure and or repairs needed info beyond the basic product ID and or brief specifications.
I went through a big old long call one time with Briggs & Stratton talking to two or three different people and got a hold of a person there who did they're absolute best to help me.
I was actually trying to find a replacement part for a Briggs & Stratton Brand 4 cycle string trimmer.
It was a camshaft and I had it in my hand with the numbers on it etc and had all the numbers on the machine and the engine too.
After extensive digging, and I think this employee actually called me back later, they were able to ID the part but unfortunately said they were actually none of them ever made as parts.
They uncovered the fact that none of this was ever made by Briggs & Stratton but simply contracted by another manufacturer to make the entire machine.
It was kind of a weird one-off model thing and it seems like there weren't twin Parts sitting around in the Troy-Bilt or other brand four cycle trimmers.
Technically, there could have been but officially no replacement parts wherever ordered, made, or packaged as individual parts for this item so we were at a dead end.
It would have been faster and probably just as accurate to put a post on a group like this or the other larger more popular for him at the time or ask a couple of people who repaired lots of these items.
At the time, I hadn't messed with a lot of these and I stopped doing all of those little ones because I found it's not cost-effective for my shop or the customer but someone who did a lot of these types of items would probably take one look at it I know exactly who made it, just like I do with mowers for about a 3 decade.
I understand people's desire to jump through hoops if it does get them the info they need like it's a last resort but unfortunately it's usually not a last resort and if they would go with the most likely and common or efficient approach to begin with they wouldn't even need to consider trying to call the original manufacturer which like I said, usually yields little to nothing.
For me, it's about the same as trying to put a non OEM brand belt on a machine.
I don't even really consider it an option because it's proven problematic so many times.

Glad that worked for you but I refuse to deal with equipment manufacturers because normally it's just a waste of time.A few years ago, I needed the engine info on my Gravely 260Z.
