I was wondering if anyone knows what the head bolt torque is for a newer briggs 22hp v twin engine is. My repair book is older and doesn't mention the specs for this engine. The main difference is thar the head bolts are not the typical 1/2in bolts I usually deal with, they are smaller 3/8 bolts.

The engine number is: 44N677-0042-G1

Thanks for any help you can provide!

2. Install cylinder head assembly, Fig. 23.
a. Torque head bolts in sequence shown to 220 in.
lbs. (25.0 Nm).
3. Install push rods. Make sure push rods are inserted in
recess in tappets.
Note: Intake push rods are aluminum.

Just to comment on your repair information: I updated much of my small engine service data by going to Ebay and purchasing CDs to use in my laptop. I have quite a few that cover old and new models along with some for ATV's and Kawasaki mules I work on.

Um, missing a step. Need to lap the head and block area where the head gasket sits. 3 step bolt torque is kindly advised. Every head I've pulled after checking were never flat. Intek engine owners pay attention here. Those love to toss head gaskets.

So 18 foot pounds of torque in this case. Make sure to gradually tighten bolts in a sequence. Also, lap valves and remove carbon as needed. I always use copper spray on head gaskets.

Sorry for the late response, but thanks everyone for the input. I did clean the cooling fins. The head failed because of a bunch of debris packed into the fins. It ended up having a valve guide back out and bending the pushrods. Luckily it wasn't my mower but I was fixing it for a neighbor.

All caused by dirty slash clogged cooling fins.

Briggs changed the torque to 300 in/lb, but never updated the service manuals.

Specifically is this for Intek engines, twins or??? That is 25ft lbs converted.
