- Heads are fully assembled with springs and valves
- Designed for ’06-’16 engines with stock crankcase
- Good for touring bikes and other heavy vehicles
- Works well with engines of 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 0.650″ 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
- Will not work with S&S compression releases in a late model twin cam that has Harley Davidson® ACR (Automatic Compression Release) already installed.
- Not compatible with ’14-’16 FLHTK/FLHTKL, FLHTCUTG Twin-Cooled motors or ’17 touring models.
- Not for models with OEM compression releases.
- Must use S&S rocker boxes if S&S compression realses are used.
