How do you know what the compression is going to be without knowing what head gasket you're using?

Head gasket choice depends on a few things, like quench, desired SCR/DCR, piston choice, combustion chamber volume, etc.

the piston kit said 11.17-1 with 58 cc heads. i assume that would be with a stock thickness gasket the heads have been milled slightly and have bigger valves so i figure some where aroun 11.5 just a ball park i am looking for a good gasket for that set up thanks

Lots of assuming going on. You need to get some hard numbers.

Piston size (-5cc?)-
Bore?-
Stroke?-
Deck height?-

FWIW, I run an Impala head gasket at .028" with a zero-decked block and 53cc heads resulting in just under 13:1 static compression.

Have you consulted your engine builder yet?
