Bingo... obviously you keep a comfortable distance from the egde of detonation/pre-ignition. Obviously more to it than just tune when it comes to the mechanics of it, but tune is a huge factor.
I'll add its not just gaskets you hurt, that tune can save or hurt things below the pistons.
Certainly not an E-head only issue.
