Every cylinder head we sell is fully remanufactured to meet or exceed OEM specifications:

  • Deep Clean – To start the remanufacturing process, every head is fully disassembled and hot tanked (cast iron) or thermally cleaned (aluminum)
  • Inspection – Magnaflux testing uses magnetic particles to inspect metal, checking for microscopic cracks and fissures that will cause long-term failure. All parts are visually inspected as well.
  • Machining and New Parts – Deck surfaces are CNC machined and new parts are added. New parts inlcude lifters, gaskets, Viton™ valve seals, and soft plugs.
  • Camshaft Verification – Every cam is deep cleaned, inspected, straightened, re-centered, reground as needed, polished, and cleaned one final time before being reinstalled.

Because of our rigorous remanufacturing process, we have the industry’s best warranty options, with a 7 year, 1 million mile no-fault warranty available.
