I had removed mine and upon reinstallation by the machine shop the threads wanted to pull out at 45 ftlbs. Had to have all 16 holes heli coiled, problem solved. They were new at the time.

I've also seen people put the studs in with an impact wrench, and even though they don't really crank down on them, the hammering action breaks the threads loose.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
