ARP makes a longer bolt and its resuable. its like 28 bucks. to soem its not worht hte money but was for me.

i would never apply heat to the crank snout but this is me. Longer bolt does help get the pulley on. Some have stripped the first couple threads out of crank by trying to pull it on with the stock bolt.

I used a GM tool kit once for the GenIII motors and it came with a long bolt tool to get the pulley seated.
