It is for good reason that virtually every top professional engine builder relies on ARP Pro Series head studs for their all-out competition powerplants. 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. 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-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. 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.

Features

  • Premium quality heat-treated 8740 chrome moly steel
  • Precisely heat-treated to 200,000 psi
  • Centerless ground to make it as close to perfectly concentric as possible

Benefits

  • Cylinder heads literally glide into position and are perfectly aligned
  • Thread rolled after heat-treat, which gives them about 1000% (that’s ten times) better fatigue strength
  • High Performance head bolts are available with a reduced wrenching hex or 12-point and wide area flanged head that eliminates the need for valve train removal to facilitate cylinder head retorquing.

Applications

  • 1998-2002 Pontiac Firebird Formula, Trans Am
  • 1997-2003 Chevrolet Corvette
  • 1997-2002 Chevrolet Camaro

Whats in the box?

  • Chevrolet Small Block LS1 pro-series 12pt Head Stud Kit
