Modifing your diesel engine will push the limits of your head gaskets and usually will cause them to fail. Removing the factory OEM Head Bolts and replacing them with ARP Head Studs will help to overcome this problem. Studs are made from 220,000 psi tensile strength chrome-moly steel, adding 12 point nuts and parallel-ground washers. They are manufactured in ARP's Santa, Paula, CA plant from ARP 2000 material, with threads rolled after heat-treat to provide optimum fatigue strength., and are centerless ground to assure perfect concentricity. The ends of the studs are broachedto facilitate easy installation. This feature also enables the cylinder head to be removed in tight quarters. Everything is black oxide finished for extra durability.
All this will provide the clamping force required to keep cylinder heads from lifting due to higher combustion pressures.
