We had a failure a couple yrs. ago with some ARP 8740 bolts, but they were older and i don't know how many times they had been torqued. I do know that since then i'll not put an engine together without new bolts, and i guess that the question were these new bolts or had they been used before?
I'd definately get in touch with ARP, but they are butt holes to deal with unless you're a big name racer.
