ARP Head Studs
ARP uses premium grade 8740 alloy
that is rated far superior to “aircraft” quality. Each stud is
precisely heat-treated to 200,000 psi. Following heat-treat, each
stud is centerless ground to make it as close to perfectly concentric
as possible. This involves about ten very slight
cuts and results in an exceptionally straight part (lesser quality studs are not even centerless ground
– the material is thread rolled in bar stock form, usually prior to
heat-treat).
Because ARP studs are manufactured to such exacting tolerances, gaskets and cylinder heads literally
glide into position and are perfectly aligned – something that
won’t happen with inferior quality head studs.
