If you want to know exactly you need to measure CR and valve clearance, I would assume since 318 piston sit pretty far down in the hole should be fine.
There's different head gasket thicknesses you can fine tune to what you want.
Engine still has Stock and standard bore pistons from the factory. The head gasket that was used and the one I was going to use again with stock heads was the FEL-PRO 8553PT perma torque blue gaskets.
