True, but in hindsight I think I did feel it. I used to think I had an ignition problem, sort of a rough acceleration... you can search back and find threads about it. Now I don't have that any more. I'm thinking that was detonation.
My piston blew because of the 36 degrees of timing and the excessively high AFR. It was 15:1 at 5lbs, when I sealed it up and it boosted like it does now... who knows what the AFR went up to.
Also quench is less important in blown apps so I hear.
If Ben has less than ideal quench right now, which is likely with his high compression franken-LSX, than he can kill two birds with one stone. Lower the CR and get ideal quench.
