Default H22 Pistons/ H23 Compression change



If I were to get H22 pistons for my h23 block. If the H22 pistons compression ratio is 10:1:1, what would that change to in the h23? Would the CR go higher or lower?

USDM H22's put it at 11.1:1
JDM H22's put it at 11.5:1
TypeS H22's put it well over 12.x:1

Satan_SRV is the math-wiz that figured all this out, a search should bring up his post on it

I am currently puying the parts to drop H22 pistons in right now, hopefully I can tell you how it goes soon.

Doesn't the H22 and H23 have the same block just different internals?
