Wow, I thought my 3.3 with a spun rod bearing was a mess inside - sorry...

Factory rod bolts stretch permanently to achieve desired tension and are one-use only. This is pretty common for stock rod bolts on many auto engines.... That said, stock ones are the weak link of the entire 3.2/3.3 motor - the SC has bigger rod bolts - but usually fine for most people unless/until over-rev'd (aka "the moneyshift").
ARP rod bolts (and almost certainly Raceware too, but do your own checking) are re-usable, unless stretched beyond their point of elasticity, either in service or when fitting. Which shouldn't happen. They're made from better material and are stronger than the factory part.
