I had one break on me. There's a good 1/4" sticking out of the head, but I have left it that way for a month or so. It happened while the car was sitting one night. I backed the car out of the drive way and I saw something, so I got out to see what it was.. It was 1/2 the stud and nut. Popped the hood and sure enough.
Pretty much the same story here, I pulled the heatshield and there were two nuts and a snapped off piece of stud just sitting in there. ARP says it's because of the heat from the turbo but everyone I tell says the same thing "I've never seen ARP hardware break". Neither did I until it did.
