If you do not have access to a bolt stretch gauge and prefer to depend on torque, ARP recommends torquing all your rod bolts at least three times, with moly-lube applied, before pre-fitting and assembly. This is because each time the nuts are torqued into place, the threads on the bolt and nut are polished a little bit. Each time the rod is assembled, the reduction in friction between the threads indicates the same amount of torque will stretch the bolt a little more. After three times, the drop in friction will level out. This is the point at which ARP's torque recommendations are ideal.
