S&S CYCLE 89 cc Super Stock® Cylinder Heads — Wrinkle Black – 06-17 Dyna, 03, 06-16 Touring, 06-15 CVO, 10-16 Trike, 06-17 Softail

Fully assembled heads with springs and valves, designed for '06–'16 engines using the stock crankcase. 🔧

Ideal for touring and heavy bikes; they work well on stock-displacement engines and are best for slightly larger stroker or big-bore engines up to 110". The combustion chamber provides a slightly higher but still manageable compression ratio in larger engines.

Large 2.000" intake and 1.605" exhaust valves maintain port velocity for strong low‑ and midrange response while supplying enough air for increased performance.

High-performance valve springs allow the installation of camshafts with up to 0.650" lift, and intake ports flow 264 CFM compared to stock heads at 182 CFM. Compatible with stock rocker boxes, exhaust, and intake manifolds.

Made in the USA. Will not work with compression releases in a late-model twin cam that has Harley Davidson® ACR already installed. Not compatible with '14–'16 FLHTK/FLHTKL, FLHTCUTG Twin-Cooled motors or '17 touring models. Not for models with OEM compression releases; if aftermarket compression releases are used, compatible aftermarket rocker boxes must be installed. ⚙️
