Harley Davidson Screamin Eagle Pro CNC Ported Factory Heads With Valve Upgrade – 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 char- acteristics of air and fuel to provide enhanced performance. But it doesn’t stop there, oversized (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 bath- tub’s 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 instal- lation of Automatic Compression Release (sold separately).
