Engine build on the brain

The heads are open chamber iron econo W2's. Already spent the money on porting ,rockers, headers and intake so they are staying. Thought I mentioned it, sorry for the confusion
Help me out;
why would you "set" the pistons down .020 and then top it with a fat .054 gasket. With flat tops and closed chamber heads, this gets you a Quench of .074 which is useless for it's intended purpose. Generally, no quench requires a drop in SCR of 1/2 point to stay out of detonation.
