Compression ratio?

[02 281 GT]

I'm curious as to what kind of a compression ratio this kit (dome pistons) and this kit (flat top) would net me with some AFR 185 heads with 58cc combustion chambers. Any ideas? This would be on a .030 over 306. I'm looking for at least a 10.5:1 C/R for the Cobra.

I probably should have posted this in tech...

You would probably have to go to the dome kit to get over 10.5:1, or mill the heads and or block a lot.
