Briggs head gaskets

I've got to pull the head on one of my Briggs 15.5's to clear up a valve problem , and NAPA can't find my model # for a new head gasket ,it's 31P77 367E1 and they can't find any with the P in the model # / do all of the 31's take the same gasket ????

Head gasket is 796584. Why not shop at a dealer?

Cheese could point you on that one, Goat. He's a Georgia guy, I believe.

Probably 31P707, pretty standard riding mower engine number.

Had backfiring through carb so with the valves properly adjusted it's going to be a defective intake valve or somthing wrong with it / pulled the head it looked good so I sat the head with the combustion chamber pointed up and filled it with raw gas with several layers of paper towels under it , ... 2 hrs - no gas leaked through either valve ????? cam???? gremlin ???/

I'd have to hear it, or have a more detailed description. Small popping backfires at random, surging engine with the backfires, regular loud bangs, etc... Could be carburetor, loose valve seat, or other problems.

My bad ,, sorry for all the confusion , this was the first ohv engine that I've worked on and I let the unique style get the best of me , it now has newly lapped valves / new head gasket / new exaust gasket / new intake gasket / AND A NEW KEY ON THE FLYWHEEL - runs great . I broke the very first rule and it cost me .
