Been a few too many years 4? to recall but the last set of arp rod bolts I put into oem type rods were either tq or stretch and came with an instruction sheet with specs n stretch.

If your trying to stretch your rod bolts I think you can find it in this link with your pn. I pre stretched mine twice then set the third time, not sure if it was needed but its still running.
