Fully assembled with springs and valves, these heads are built for reliable low- and midrange performance. 🔧
Designed for '06-'16 engines with a stock crankcase and ideal for heavier touring machines or larger stroker and big bore engines up to 110".
- Large 2.000" intake and 1.605" exhaust valves maintain port velocity for strong low- and midrange response.
- Intake ports flow 264 CFM versus stock 182 CFM for improved breathing.
- S&S® high performance valve springs allow camshafts with up to 0.650" lift.
- Combustion chamber yields a slightly higher but manageable compression ratio for larger-than-stock engines.
Compatible with stock rocker boxes, exhaust, and intake manifolds when used without compression releases; must use S&S rocker boxes if S&S compression releases are installed.
Made in the USA. Not compatible with models that have OEM compression releases or certain late-model touring engines, including '14-'16 FLHTK/FLHTKL, FLHTCUTG Twin-Cooled motors, or '17 touring models. ⚙️🇺🇸
