high compression
Static compression doesn't determine "streetability" or "probability of detonation." That's the job of the dynamic compression ratio which incorporates camshaft valve events paralleled with static compression dimensions.
For what it's worth, I'm running 12.6:1 static, 9.6:1 dynamic on 93 octane with 0 KR.
