Iv run valve springs in a high rpm solid roller gas race engine. They use to last 2 meets after treating they last a whole season. So i do everything now as it cost me nothing call it bs i don't care i do it because i can and it's worked.

I'm no expert but going through all the trouble of building a motor it would be stupid to not put Carrillos in if your going to make any power or you will be doing it again:spit:

THere is 1 small physical difference between lb7 and 04/05 lly pistons, i have yet to break a modded lly piston at 1k hp so i dont beleive it to be a strength difference at all!
