Heads are assembled with Original Equipment valves and high-performance valve springs that support cams lift up to .585. 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 promoting improved. But it doesn. End there, the proven stock valves rest in reshaped valve seats to further improve flow rates. CNC Ported Heads offer a cost-effective approach to upgrading the performance of your motorcycle.
The head gasket surface has been milled to maintain stock combustion chamber volume 59.9cc, which results in compression when used with Original Equipment pistons. Compression can be increased with the installation of Screamin Eagle high-compression pistons. All EFI model's require ECM calibration. For race application only.
