No longer is it necessary to order the Ford Pinto head studs kit and also buy the appropriate washer separate.
This kit is assembled from individual ARP parts and includes the appropriate washers. This kit also features ARP 6-point (hex) nuts instead of the typical 12-point nuts.
Its been long established that ARP fasteners require re-torqueing on a regular basis. In our experience, this could be due to the 12-point fasteners having very little material. The 6-point nuts have must more material to them and are less prone to thermal expansion, providing superior torque retention.
