ARP Pro Series cylinder head studs are cold-forged to ensure molecular integrity. They're heat-treated prior to thread rolling and machining. ARP Pro Series kits are also available with 12-point nuts, and all studs come complete with hardened parallel washers for an even load distribution and accurate torque readings. With hundreds of models ready to ship, these cylinder head fasteners can be ordered for virtually any style engine.
