When I first started using ARP rod bolts in stock 440 rods the instruction said to torque, torque them to the torque spec three times with the lube and untighten them three times BEFORE using a stretch gauge work
All the ARP rod bolt instructions sheets I have show different stretch lengths for the 7/16 rod bolts depending on the under head bolt lengths work scope
No matter what not all bolts, even made by ARP, are exactly the same and equal on torque needed to stretch them exactly the same twocents up
