ARP Head Stud Kit
ARP uses a premium grade 8740 alloy that is rated far superior to "aircraft" quality. Then, each stud is precisely heat-treated to 200,000 psi. ARP studs are thread rolled after heat-treat (a very common industry practice). All kits come complete with hardened parallel-ground washers and high quality nuts.
