To overcome head gasket failures that can occur in diesel engines employed in truck and RV applications, industry leader ARP has introduced extra heavy-duty head studs for the popular Ford, Dodge and GM powerplants. These ARP studs are rated at 220,000 psi tensile strength, and provide the clamping force required to keep cylinder heads from lifting due to higher combustion pressures. The studs are manufactured in ARP's Santa Paula, CA plant from proprietary ARP 2000 material, with threads rolled after heat-treat to provide optimum fatigue strength. They are centerless ground to assure perfect concentricity. The ends of the studs are broached to facilitate easy installation. This feature also enables the cylinder head to be removed in tight quarters. Also included in each kit are heat-treated, chrome-moly steel 12-point nuts and parallel-ground washers. They are black oxide finished for extra durability.

Good parts, but could use better instructions and extra Lube.

We know ARP makes great fastners, but 26-studs and only one packet of ARP Lube? Plan on ordering extra lube unless your really stingy applying it. Also the instructions should point out that the rocker box needs clearancing for the rear center stud nut, and the longer studs go to the exhaust side of the head. Also a good idea to tap the blocks holes with a bottoming tap before installing the studs. If replacing with the heads on, a 6" long 12mm bottoming tap should be used.
