I think Steve commented on this problem.

They (Sup) are installed using blue Loctite in the case and anti seize on the nut. They are designed differently but I wonder if loctite may cure the ARP loosening problem?
Hi Jim:

A clarification is needed.

The ARP studs never loosened from the case as long as they were installed properly. The head NUTS were the ones that loosened up and in a few cases; backed up almost all the way off the threads.

One well known engine builder suggested to me that I failed to torque them properly and I told that fine gentleman that not only di I know hoe to use these tools, but our torque wrenches are checked & recalibrated at least once a year. We use Snap-On split-beam models as well as the new electronic ones...

Hope this helps,
