Send it, you can get away with that compression by using aluminum heads. I built a zero deck 360, .027 Cometic head gskt & eddy heads, ran it at 32 degrees total timing. No problem running on pump 91 octane premium. Had it in a Dart Sport, ran 11.30's.

I‘ve said this before but since it keeps getting repeated I’ll repeat this.

Aluminum heads will NOT take any more compression than iron heads. That’s another myth that needs to die a quick death.

Unless of course you want to pull a 3 mile long 6% grade in high gear. If you do that you should be playing golf and not building or driving performance cars.
