Description
S&S Cycle - 90-1106 - Cylinder Heads - 89 cc - Super Stock® - Twin Cam
Features
- Heads are fully assembled with springs and valves
- Designed for '99-'05 engines with stock crankcase
- Good for touring bikes and other heavy vehicles
- Works well with stock displacement, but are ideal for somewhat larger stroker or big bore engines up to 110"
- Combustion chamber provides a slightly higher than stock, but still manageable compression ratio in larger than stock engines
- Large 2.000" intake and 1.605" exhaust valves maintain port velocity for good low and midrange response, but supply enough air for slightly larger engines to perform to their full potential
- S&S® High performance valve springs allow the installation of camshafts with up to .650" lift
- Intake ports flow 264 CFM (Cubic Feet per Minute) compared to stock heads at 182 CFM
- Compatible with stock rocker boxes, exhaust, and intake manifolds
- Made in the USA
- Must use S&S rocker boxes if S&S compression releases are used.
