Safe to re-use ARP head studs?

[noodl35]

I've already re-used these studs 2 times now and I may use them again on the same motor. Do you think they have stretched any and may have to get new ones? What do you think. BTW, what are the dimensions or length of the sr20det head studs to see if they have stretched.

i think you can find the dimensions at www.zeroyon.com in the fsm

do youreself a favor , don't wonder get new ones!! We are talking headbolts here they do stretch even the ARP . Rather be safe than sorry.
