The head bolts are the same on any of the B/RB engines. You can get them from Chrysler, from ARP - a very well known fastener supplier in the aftermarket performance partsm, you can probably get them at any GOOD hardware store if you show them the bolts, specify the grade 8 and make sure the head style is identical. Id just go to Mopar Performance or Summit or any of those online parts places and buy a set. The other alternative is take a set from another engine, they generally dont wear out. Mikey 62 Crown Coupe
