The instructions,
HEAD BOLTS or STUDS: High quality head studs or headbolts with hardened washers must be used to preventgalling of the aluminum bolt bosses. Edelbrock Head Bolt Kit#8555 includes two longer-than-stock bolts which must beused with these cylinder heads. If you use any other headbolts, you must use the two head bolts and washers suppliedwith these heads in position #5 in Fig. 1. This position willnot accept stock length head bolts
ARP bolts or studs are the best way to go in my opinion.
