360, You think it'll run on pump gas?!?!

So I'm buildin a 360 and I'm at the point on deciding what thickness headgaskets too go with. I thinking I'm right on the verge of being able to run pump gas (93), but the fact I'm running iron heads makes me think 100 octane might be more realistic. Wanted to give y'all my specs and see what you think.

-0.030 over 360
- speed pro hyper pistons, sitting .005" below the deck
- J heads, ported, gasket matched, bowls blended with 2.02/1.60
stainless valves and 64-65cc chambers (cc'd)
-lunati voodoo solid cam 235/243 @.050 .526/.546 110lsa
-harland sharp 1.5 roller rockers
-edelbrock torker II 340 intake
-holley 750dp

Based on the compression ratio calculators i've found on the web, they're all saying I'm gonna be about 10.8-11.0:1 if I use a .039 thick head gasket. Should I run a thicker gasket, or do you think I'll have more fun/be happier overall with the higher compression? Appreciate any input.

Thanks,
Tom
