ARP 135-3609 BBC Head Bolt Kit

Description

These fasteners deliver superior strength and meet the arp zero defect - zero failure quality standard. All pro series head bolts have a reduced wrenching hex or 12-point head and wide area flange to eliminate the need for valve train removal for cylinder head retorquing and permits the use of larger diameter valve springs. Arp pro series head bolt kits are application specific - designed for use with typically competition only components. All high performance series bolts are 180, 000 psi which is 15 percent stronger than grade 8 and kits come complete with hardened parallel-ground washers. Most applications have undercut short bolts that can help eliminate head gasket failures through providing more stretch to compensate for the additional compression of gaskets. Hardened and parallel-ground washers are included with each kit to ensure even load distribution and accurate torque readings. Professional series all pro series bolts are cold-forged to ensure molecular integrity, heat-treated prior to thread rolling and machining, and are rated nominally at 200, 000 psi. These fasteners deliver strength and meet the arp zero defect - zero failure quality standard. High performance series high performance head bolts are available with a reduced wrenching hex or 12-point and wide area flanged head that eliminates the need for valve train removal to facilitate cylinder head retorquing.
