CNC - Well since the piston to deck clearance is already 0.015" with Tom's pistons, then the highest quench I can have is 0.056" with that 0.041" gasket and the lowest being 0.041" if I zero decked it. So no matter what I do the quench will be in the correct range.
Wouldn't my best course of action be to deck the block as little as possible to clean it up and decrease quench height some. And then just compensate the increase in compression from decking by opening up the combustion chambers to lower it back where I need it?
