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 Percent (that's ten times) better fatigue strength than those studs that are threaded prior to heat treat. This procedure (done only to the shorter studs) more equalizes the "stretch" of both studs, which makes for a more consistent clamping force and one that compensates for head gasket compression when the cylinder heads are installed. Thread Rolled After Heat Treat, Which Gives Them About Ten Times Better Fatigue Strength Than Those Studs That Are Threaded Prior To Heat Treat.
