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 faciliate cylinder head retorquing. All High Performance Series bolts are 180000psi (which is 15% stronger than Grade 8) and kits come complete with hardened parallel-ground washers.
