River City Diesel Platinum Trademarked 5 Layer Head Gaskets are built side by side with Genuine Ford Gaskets. Many installers prefer these over the black onyx due to the proven reliablity factor that comes with the Ford Gaskets. The only difference between Ford Gaskets and Platinum is the Ford Gaskets have a blue dye sealant while the Platinums have a charcoal color.
The ARP 250-4202 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 center-less 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, chromoly steel 12-point nuts and parallel-ground washers. They are black oxide finished for extra durability.
The Platinum Head Gaskets have been proven to handle over 800RWHP when used with ARP 250-4202 Head Studs.
