figuring out compression

How do you figure out the compression ratio of an engine? I am running a 350 with stock pistons, moly rings, some 60 CC chamber heads from a 305, stock intake and 750 cfm Qjet. I was told by a couple guys that I have to run 92 octane because of the heads I chose. Can anyone fill me in on how you calculate the compression
