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.
That is just what he got for deck on the few blocks he has checked, you could have more or less, but you need to physically check it to verify. But yes, if you have .015" deck clearance and only deck the block the minimum and you still have too much compression, you don't have many other choices to reduce it, so cutting a dish in the piston may be an option.
