Head Bolts

High strength ARP stainless (chromoly studs are non-stainless).

The fluted shanks allow the studs to stretch to prevent the threads from pulling out. The bolts don’t loosen and oil leaks are eliminated. Special triangular reduced shank studs help align the head with the cylinders. Stock heads require installation of US 3/8″ coarse thread TimeSerts or Helicoils.  Full Auto heads with British thread Helicoils need either British thread triangular bolts or conversion to US threads with oversize TimeSerts (“Big-Serts”).
