CNC Ported Heads offer a cost-effective approach to upgrading the performance of your motorcycle.

  • The intake and exhaust ports are meticulously machined for smooth surfaces, improving the flow characteristics of air and fuel in order to provide enhanced performance
  • But it doesn’t end there, the proven stock valves rest in reshaped valve seats to further improve flow rates
  • The combustion chambers have been machined for smooth surfaces and feature a blended radius on the bathtub edge to reduce detonation by eliminating hot spots and promoting improved combustion
  • The head gasket surface has been milled to maintain stock combustion chamber volume (59.9cc), which results in stock compression when used with Original Equipment pistons
  • Compression can be increased with the installation of Screamin’ Eagle high-compression pistons
  • Heads are assembled with Original Equipment valves and high-performance valve springs that support cams with lift up to .585."
  • All EFI models require ECM calibration (priced separately)
  • For race application only
