340 Head gasket

I bored my 340 .020 over, KB pistons, Eddy 60179 Heads with the Felpro .039 Compressed head gaskets. Cranking compression 165 ish. I'd have to check my notes. I'm just wondering how mush compression would bump to with the .028 gasket.
Bump it to just about right :)
iam 169 cranking comp power timed on 94 no problems
