Hmmm. I have reused head bolts. ARPs. No problem. Never lost a head gasket. Some retorque head bolts after running a motor a bit. I dont but... . I have used torque to yield bolts. Torque to x ft lbs and tighten x degrees more. High dollar wrench. I will check into this. Maybe i just been lucky. Gen 2 hemi bolts cost! Always learning something.
