Ok I will post some pictures after I go take them, sun is finally out, I feel like a groundhog.
Remember the dampener is on tight but it is an interference taper fit that does the main holding, just because the bolt is out the dampener does not come right off.
The high force used is because of the vibration it sees and the side force from the belt. Once it is on tight an ARP super bolt is over kill. I have 2 ARP's with chewed up threads form a bad Ford assembly job with a big impact gun that ruined the internal threads that I had the same problem with. Ford only has to have it go together once. I retapped the best I could but the bolts did not have the full reach of threads in the deep hole and felt iffy so I put in a full depth stud and now I have to be careful because I can now sink the pulley on too deep since I am not using the internal threads to pull the dampener down.
It worked out well and I like it better than the bolt now.
