The cafine just kicked in ( morning down here )
See if you can get your hands on a bore-o-scope
Shove it down the spark plug hole and look for the cross hatching on the cylinder walls
When you said to remove the rocker covers and do a test run, just start the mower and let it run idle at full throttle with covers off? No blade engaged just running? How long do I let her run? Thank you very much! I can get a bore o scope from my neighbor I’ll check that tomorrow and look for the hatching.

Take off the valve covers and then have someone crank the engine while you watch, you should be able to see where the head gasket is blown.
What would I be watching for? Sorry for my ignorance heh. Thank you!!

Good neighbour to have .
Engage the blades so the throttle opens up.
The usual "alert" symptom for an internally blown head gasket is very rough running the instant you engage the blades.
Engine usually backfires, blows a little smoke ( either colour ) then settles down once the speed has stabilized.
Some times it will do the same when you go quickly to full ahead then full reverse because the engine slows a little & the governor allows the throttle plate to open fully so the engine get a full lung of air thus developes maximum compression pressure

Compression blowing through the bad section of the head gasket, it pressurizes the crankcase and forces oil into the carb/intake and is burned while using the engine, you should be able to see where it is leaking. I used to start and run the engines, oil will spray a bunch more on the leak side.

That's the usual carbon build up on the piston, From the looks of it the cylinder walls look pretty glazed and shiny with a few light vertical scoring marks.

What does the scoring come from? I seen some oil in one of the pics looks like it is seeping out on one particular spot. Is that normal? What should I do next? Thank you!!

Your engine has been eating dirt
As the compression looks reasonable. time to whip the pistons out give the bore a crosshatch hone and pop some new rings in.
kawasaki parts are priced properly so it is not going to be cheap .
kawasaki have their service manuals on line and older ones are on the K & C Spares web page .
Too many chargable hours ( 6 to 8 ) for a mower shop job but you might get a discount if your local workshops have very quiet off seasons

Thanks Bert! The dirt, would that be from the elbow you referred to earlier or is it that something that will be hard to pinpoint without a professional eye? Thank you very much again for the help!
