ARP Head Stud Information
Obtaining the optimum cylinder head-to-block sealing is especially
critical in small displacement engines employing high compression
pistons or power adders like turbochargers, nitrous oxide and
superchargers. That's why ARP head studs are popular among leading
Sport Compact/Import racers.
You should know that 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. Following heattreat, each stud is
centerless ground to make it as close to perfectly concentric as
possible. This procedure involves about ten very slight cuts and results
in an exceptionally straight part. It's important to note that lesser
quality studs are not even centerless ground—the material is thread
rolled in bar stock form (mostly before heat-treat, when the material is
easier to machine). Because ARP studs are manufactured to such
exacting tolerances, you will note that gaskets and cylinder heads
literally glide into position and are perfectly aligned—something that
won't happen with inferior quality head studs. ARP studs are thread rolled after heat-treat, which gives them
about 1000% (that's ten times) better fatigue strength than those studs
that are threaded prior to heat-treat. ARP Head Studs prevent blown head gaskets and ensure optimum sealing!
