Those Stage 8 bolts are the ones I was talking about.
The hemisphere part of the tabs you install keep the bolt from backing out. The flat part of the bolt will nudge up against the exhaust tube and stop after about 1/16th of a turn, MAX.
I installed them on my 351w and they never once created an exhaust leak after about 15,000 miles of driving. I'm doing an engine pull right now. If I remember, I'll try to take a picture to demonstrate how they work.

Thanks Ryan that will help a lot.
