One thing I learned on my own is that ARP stretch is usually about 25% more torque than what ARP specifies. That convinced me that stretch is the only way to tighten a rod bolt for true high performance useage.

Any ARP fastener that is rusty should be thrown into trash because the oxidized metal will cause oxygen embrittlement, leading to a broken fastener.
X3 with using stretch method instead of the repeated torquing procedure that ARP lists with their fasteners.
