Default Compression ?

WHat compression will I be at if I run a set of stage 1 PRC LS6 heads on a stock LS1 bottom.The gaskets I will be using will be a .062-.072 thickness. I was going to run a NA setup but plans have changed and I will be doing FI instead.So I want to drop the compression to run a decent amount of boost.

Assunming 64cc, .062 will be around 10.5-1 and .072 10.25-1

if you don't have heads already the better choice would be to get a set of either 317 heads and maybe have them ported or some aftermarket 72cc heads and use a thinner gasket.
