Just to keep the record straight. I'm not sure if I'm the Steve referred to, but I did recently post that maybe my ARP head studs were backing out. I now have all the studs out, and can say that most of them were firmly in place. None seemed to back out or be loose. Two were pulled -both on No. 1 cylinder exhaust & intake toward the front of the engine.
My memory is that the height is 135mm to the top of the threads. That's what they were when I removed them. 38 ft-lbs is the same torque value I got from ARP, too. I also asked them to send me the installation sheet for that kit. ARP moly lube on the top; nothing required on the bottom - but if a sealant is used ... torque before it sets.
By the way, the hardware looks perfect after 30K miles and 5 years.
Based on what Steve said, maybe I should go back to the new style dilavar. More choices . . .
