Im game for the junkyard on Monday, then Im gone for like 3 weeks. If you cant do it then no biggie, I know you actually have a job and work. LMK, I know that one yard has some non-turbo 4g63's with plenty of plugs and sensors.
What that means is once the load is taken off the stud it will rebound back to it's original size, this is what gives ARP's there clamping force, the stud is actually pulling the two parts together instead of just the initial force of the tightening. OEM bolts will stretch and not rebount back to their original size.
