Here is an excerpt from an ARP instruction sheet of their 625 set for the S65:

"[7] A log should be kept on the original non-torqued length of each bolt. Bolts that have any permanent deformation or have increased in non-torqued length by more than .001 in. should be replaced."

This is typical for all of their rod bolts across every make and model, though their dimension specification may be different depending on application or material.

Any bolt regardless of type, material, or application has the potential to stretch and be rendered ineffective. Their process identifies any stretch to monitor the hardware's effectiveness.
