ARP Pro Series head studs are a proven choice for all-out competition engine builds, built around tight manufacturing control and consistent material quality.

  • Made from premium 8740 alloy (rated by ARP as superior to aircraft-quality material).
  • Heat-treated with each stud positioned vertically in dedicated racks, then processed to 200,000 psi to promote complete heat penetration.
  • Centerless ground after heat treatment for near-perfect concentricity.
  • Finished through approximately ten light grinding passes to achieve exceptional straightness.
  • Threads are roll-formed in bar-stock form (typically before heat-treat for easier forming).

Because they’re manufactured to exact tolerances, ARP notes that gaskets and cylinder heads can slide into place and align cleanly during assembly.
