ARP cylinder head bolts are rated at 170,000 p.s.i. tensile strength (approximately 15% stronger than grade-8) and feature a wide-area flange for improved torque load distribution. O.E.M. head bolts should not be reused when rebuilding your engine due to bolt stretch when torqued. Each hex-head bolt kit comes with hardened and parallel-ground washers.
NOTE: ARP head bolt kits cannot be used with Edelbrock aluminum heads. All Edelbrock heads include bolts.
