In stock

Got a 7m with a Blown Head Gasket? After repeated overheating the 7m head anneals and becomes soft, as well as having issues with warpage which cause the gasket to blow again shortly after it is changed. Poor surface finish from an average machine shop will also make it difficult for the new gasket to seal.

These heads are fully reconditioned with better than factory finish and additional coolant drain to assist with preventing BHG.


All heads undergo the following work:

  • Chemical Clean
  • Full head inspection -Hardness test, crack test, straightness test and all threads checked
  • Surfaced to mirror finish
  • CNC 3-angle valve cut
  • Cams clearanced to factory spec
  • Additional coolant drain for BHG prevention
  • New valve stem seals and cam seals
  • Supplied with upgraded cam cover bolts and shakeproof washers to allow correct torque to be maintained and prevent oil leaks


Head is supplied complete and assembled with valves and cams, reuse your existing cam gears, rocker covers, manifolds, brackets etc

Additional options are adjustable cam gears,  custom profile 268 degree or 280 degree cams, shim under bucket conversion and stainless exhaust studs.
