FRSPORT ARP Head Studs (102-4701) + APEXi Head Gasket 86mmx1.8mm Combo SR20DET

• 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.
