Product Details

Complete Head Kit A cost-effective alternative for upgrading the performance of your bike. The intake and exhaust ports are meticulously machined to smooth the surfaces enhancing the flow characteristics of air and fuel to provide enhanced performance. But it doesn't stop there over sized (1.875) stainless steel intake valves and stock (1.575) stainless steel exhaust valves rest in reshaped valve seats that improve flow rates. The combustion chambers have been machined to smooth the surface and feature a blended radius on the bathtubs 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 which results in stock compression when used with Original Equipment pistons. Compression can be increased with the installation of matched Screamin Eagle high compression pistons. Heads are assembled with high performance valve springs that support cams with lift up to .585. Heads are machined and threaded to simplify installation of Automatic Compression Release (sold separately). All EFI models require ECM calibration (priced separately)

Fitment: Fits 99-17 Twin Cam-equipped models. 99-05 models require separate purchase of (2) Intake Flanges P/N 26993-06. Does not fit FXDLS FLSS FLSTBS FXSE or Twin Cooled equipped models.
