You will need to choose the right head gasket when you go back together........How thick was the one you pulled off????
Any ways you need a Minimum of .040 between the piston and the head. You have one piston that is .020 out of the hole, so 40 + 20= a head gasket that is .060 or more.

Ill find out for sure what head gasket was on it tomm when Im back at the shop

Quote: The ones with the shallow machined areas around the main chambers are intended for 340 pistons like yours................

Was their a thread about this somewhere? Id like to know more, it sounds like these are the wrong heads then but it also sounds like they can be made to work with the correct head gasket.

I think like I mentioned that the valves hit the top of the pistons at some point, made VERY minor indentations, I can get a picture of this hopefully tomm.
