Im talking like 14:1 high. What would be the best way to do this? Are dome pistons available that will work?

 

Yes

I believe flat tops with proper valve reliefs will get you there(higher compression). Is it possible for chevys 4.8L V8 heads to fit on the LSX Block? Why do u want such high compression? I would say slap on 5.3 L heads and some thinner cometic heads gaskets and call it a day.

 

Flat tops will not get you there. A 10 cc dome may get you there. That is what i'd suggest. Look at TSP and a few other vendors.

You're going to need to Angle Mill the heads & use +10 domes more than likely.

 

for 14:1 you will need big domes or very small combustion chambers with a flat top =cc probably 45 or less with a flat top and .040-.045 gasket.
