    Better cylinder head gasket clamping power than stock.

    The high-performance series of cylinder head bolts from ARP are made from 180,000 psi steel, which makes them 15% stronger than Grade 8 bolts. They also feature a special wide area flange underneath the bolt head so you don't have to re-torque the heads and they provide maximum clamping power. The complete head bolt set comes with hardened parallel ground steel washers for steel and aluminum heads.
