I have two SBC blocks with several pulled/stripped head bolt threads, that Heli-Coils would not even hold torque, so I figured I'd try this kit as a last resort to scrapping the block. Apparently some of these early blocks are a lot softer than others...? I was able to repair three holes on the one block, and they took the required 70psi torque to spec... so I am a happy camper...!!! Now I will repair the other block and look forward to repairing any SBC block with same problem in the future...!!!
