ARP head stud failure.
The 75 ft lb ARP spec is not tight enough. The stud is not that strong and the diameter is "small". They can be torqued to about 90 ft lbs with no problem. Anymore and they stretch. In this case I am guessing someone attempted 100+ on them and that is not possible.
I suppose it could be a counterfit stud but it was probably just installed wrong before we got the car.
