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,
