um any of you guys know if they are one time use? cause im just rebuilding to stock spec since im going to now go rb and not going to s/c this motor. lmk so i can go buy some news if i need to....or go slap it back togther
WHen I build my lt1, I had aluminum heads and yes...it needed new head bolts. You have to replace them after every use. They are yield-type bolts. Again though, thats for an lt1...I could be wrong...
