I'm just trying to give some advice to protect your investment man! I'm not saying don't give er hell, that's why we build what we do. Most of us abuse the crap out of alot of our stuff, because we built it for that reason. It's fun to be throttle happy. I'm just givin ya a heads up of the possible consequences, I was in high school once I know how it is. I just don't want ya to be the guy with the oil trail followin him out of the parkin lot waitin on a tow truck!

.508 lift cam? I wouldnt worry about stud flex unless you are over .600 lift/ solid roller cam/ or 7000 rpm...
