Many of you may already know this but for those who are unsure I contacted ARP yesterday regarding how you can determine whether or not it is safe to reuse the head studs. I had a phone conversation with on of the tech support guys who told me that unlike the rod bolts (which you can measure to see if the amount of stretch is within allowable limits) the recommended criteria for the head studs is a subjective one. If the stud feels tight when you reach the recommended torque specification then it is o.k. If it feels soft or spongy at this torque value then it should be replaced. They subsequently sent me an email as well reiterating the same thing:
"As long as you have not exceeded the recommended torque for that
fastener, and it takes the torque and does not feel spongy, the stud
should be fine."
I just want to emphasize how important it is to adhere to ARP's recommended install instructions and torque specifications.
Hopefully this will be helpful to some of you guys.
