How Big can a 5.2 get?

Might be, I used magnum rods and KB pistons are press fit.
After a week of hard thinking Ive decided to give it a try. Ill get three pistons shaved for .006. That brings my quench in .043-.047 range with 8553pt and then I can use a thinner gasket and get final quench of ~.033 to .035
