Thanks for bringing this potential problem up for me. I got lucky. My machinist has not had a problem repeating or holding the torque values. The studs are not arp's. I am changing to the arp's to keep my blood pressure down. I think because my torque values were correct upon machining the studs can be changed without having to re-machine anything. Now if something happens to the bottom end I can blame my Source crank.lol
