I'm not sure what you compression ratio is but, if it is high, then you want to go with a camshaft with a short Lobe Displacement Angle, this will keep the cylinder pressure down. also, you can clean up the combustion chambers so that there are no heat risers were detonation can propagate itself. Call comp cams help line and give them as much info as you can and they will hook you right up. I'm sure summit it good, but I have never used them, I've only used Comp Cams, or GM replacement cams, and have never had a problem.
