It is for good reason that virtually every top professional engine builder relies on ARP Pro Series head studs for their all out competition engines. Simply stated, there’s not a better stud setup on the market today. ARP uses a premium grade 8740 alloy that is rated far superior to aircraft quality. Each stud is placed vertically in special racks and 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 procedure involves about ten very slight cuts and results in an exceptionally straight part.Socket Size(s)12mm 12pt, 4mm Allen
