Getting my compression right

Guys, I am looking to dial in my compression with some new heads. My motor:

1972 mostly-stock 360, bored .060 over with Keith Black pistons
Edelbrock 60779 Performer RPM heads (going on in a couple weeks)

I'd like a mild 9:1 or so compression, to help cool her off (this should help, right?) and let me use pump gas reliably.

So; What size cometic gaskets (heard they're awesome) will yeild what compression ratios? I saw some .075 and .120 gaskets! Seems a little thick? Am I looking in the stock range (I was told .035) or should I aim for .055 range?

I'm no engine master, so be gentle haha....
