Replace your stock head bolts with ARP heavy duty head studs. The stud design helps the head and the block equalize the pressure better thereby creating a much more even and consistent seal.
It is recommended to replace the head studs/bolts with a new set if the head bolts are ever loosened due to metal fatique. Reusing an old and possibly warped or stretched head bolts/studs will sacrifice the seal between the head and block and may cause head gasket leak.
This is a great an easy upgrade when doing an engine rebuild or building a race motor.
The kit comes with: studs, washers, nuts, and assembly lube
