im curious as to how many times you can reuse them

 

Ideally once. But you could use them more then once if you wanted.

 

As long as you don't ---- the bolt heads up you can continue to reuse head bolts. Example, don't use an impact on them to get them on or off. Just try and be carefull.

I always reuse head studs while working on N/A cars, chase them with a die and wirebresh them off. Good as new.

 

Yeah just torque them correctlly and you shouldnt have any prob with them stretching.

 

ive reused them twice and they held up fine;thanks for the info

 

oh yeah, i was talking about using basic factory bolts (with i'm sure a lesser tensil strength when compared to aftermarket performance ones).

It's never a bad idea to run a die over the threads, then tap out the holes on the head. Makes the threads nice and crisp (if that's an appropriate word to use).
