Description
The ARP 256-4001 head stud kit is made for Ford Modular 4.6L/5.4L 2V/4V engines.
Head studs clamp the cylinder head more evenly and more accurately than head bolts. A stud is threaded into the block once and stays put, so torque applied to the nut goes into stretching the stud and not into twisting it. That gives a more consistent clamp load across the head gasket, which matters most on boosted, high-compression, and race engines.
This kit uses ARP2000, an alloy rated at 220,000 psi tensile strength that delivers a higher clamp load than standard 8740 chrome moly studs.
