yea factory stud is 22 ft lb. I had to remove the heada to have it pulled so it lead to refreshing the top end and cam lifters you know. I still have the rest of the old ones i might take it to summit and see if they can match it up to something they carry. It's the only thing i can think to do other than buy another set from prw. but since summit carries studs like this i figure it's worth a try. Poly locks and rockers are still in good conditions, luckily nothing else broke when it happened. I would like to get them back in because when they were working properly you could tell unfortunately you can tell when they break to. i'm not putting the company at fault just the dumb ass tech that told me the tq spec.
