Supercharged 370ci CR

I am gathering parts to build my supercharged 370 CI for my 99Ta . Lq9 & LSA heads , lunati 6.125 rods, stock crank and wiseco piston . Here is where it is confusing. With 11cc dish piston I will be at 9.2 Cr with a .051 head gasket . But if I go to the next piston is a 3cc dish I will be 10-1 Cr . Witch is in my book to much . Right ? Am I looking to far into this, what shood I do and what CR are u centrifugal supercharger guys running ? I am using a Novi 2200 SL supercharger, and 93 octane gas ⛽ with m6 gearbox

I think 10:1 compression on 93 octane would be okay as long as the tune is good.

If your going to street drive this more than a track car I would go 10:1 and add a meth injection kit. You should have no problems if your tune isn't crazy aggressive. I'm at 9.9:1 compression with my new 383ci and it is way more crisp out of boost VS my old low compression 347ci.
