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; 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 bathtub’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 ® highcompression
pistons. Heads are assembled with high performance
valve springs that support cams with lift up to .585".
Heads are available as a complete factory-assembled kit, or
your new bike’s low-mileage heads can be factory-updated to
these specifications. All eFI models require eCM calibration
(priced separately). For race application only.
