Description

Features

• 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

Notes

• 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 releases are used.
