Read the whole thread "
ARP STUD INSTALL BLOCK THREAD FAILURE "
and so no mention of another possible cause. ARP now uses the hex on top for finger tight installation. Is it possible PO did not install some full depth due to friction? Seeing how much stud protrudes thru nut before torquing would be clue. Think difference in thread angle and lube on nut/washer would prevent turning stud deeper while torquing. Chasing threads with real tap probably aided in pull out. Don't mean to bring back dead thread but it was never resolved.
