Modified Trucks usually will have higher combustion pressures than there stock counterparts. This higher pressure could cause head gasket failure from cylinder heads lifting and head bolts stretching. Securing your heads with a set of Chrome-moly Steel ARP Studs rated at 220,000 psi tensile strength is your solution. Clamped down with 12-point nuts and parallel-ground washers. Manufactured in ARP's Santa Paula, CA plant from proprietary ARP 2000 Material, each kit is heat treated, black oxide finished for extra durability then the threads are rolled to provide optimum fatigue strength.
