ARP Head Studs - it is for good reason that virtually every top professional engine builder relies on ARP Pro Series head studs for their competition engines. Simply stated, there's not a better stud setup on the market today.
For starters, ARP uses a premium grade ARP2000 alloy that is rated far superior to aircraft quality. Each stud is placed vertically in special racks and precisely heat-treated to 220,000 psi. This procedure ensures complete heat penetration and the results are far superior to those lesser quality studs from other manufacturers who just dump pieces in a basket and hope for the best.
Following heat treatment, each stud is centreless 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. Note that lesser quality studs are not even centreless ground, the material is thread rolled in bar stock form (mostly before heat treatment, 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.
ARP studs are thread rolled after heat treatment, which gives them about 2000% (that's twenty times) better fatigue strength compared with studs that are threaded prior to heat-treat (a very common industry practice). It costs a lot more to do it this way, because it's tough on tooling, but the results are well worth the extra effort.
You won't find a better quality stud on the market from any other source. Look for ARP stamped on each stud as your assurance of quality.
