If you where to use a 72cc head and a flat top piston then you would end up with 10.2:1 compression which on a motor with alm heads is easily run off of pump gas, heck my 11.2:1 CR motor can and has run on pump gas.

Dont let a good quality dished piston fool you, they have D dished pistons now, they are not like the old O oval dished pistons that had horrible quench pads. the D dished pistons are shaped so that they keep the same style quench pad as a flat top. I had 18cc dished pistons and made just over 500hp on pump gas with them, these are the same ones that I have in my gargae that still look brand new.
Thanks I'll keep this in mind, some of the combos I've seen use the 18cc dished so I might end up going that way
