BOLT SPECIFICATIONS
ARP High Performance head bolts have a wide area flanged head that eliminates the need for valve train removal to facilitate cylinder head re-torquing. All High Performance Series are 180,000 PSI (which is 15% stronger than Grade-8) and kits come complete with hardened parallel-ground washers.
FALCON TECH NOTE: We recommend using head bolts over head studs for applications that have a master cylinder or other items protruding inside the engine compartment which may prohibit the removal of the cylinder heads while the engine is in the vehicle.
