Engine Mechanical / Electrical / Compression ratios

Hey fellas got a question, I've got a .030 over 454 running flat top pistons, and a set of 291 107cc closed chambered heads. Looks like I'm going to have to do a rebuild, I'd like to put some higher compression pistons back in it. But I'd like to get an idea of where it's at now compression wise and at what compression ratio do you need to step up to above 93 octane?
