S&S CYCLE 79 cc Super Stock® Cylinder Heads — Silver, fits 88–103 in³ (up to 110 in³) – 06, 11-17 Dyna, 06-15 CVO, 10-16 Trike, 10-11 Touring, 07-17 Softail

Fully assembled 79 cc cylinder heads with springs and valves for straightforward installation. 🔧

Designed for stock 88–103 in³ engines and mildly modified engines up to 110 in³ to improve low- and midrange response.

Moderately sized 1.940" intake and 1.575" exhaust valves maintain port velocity for strong low- and midrange torque.

High-performance valve springs allow camshafts with up to .650" lift for aggressive valve events.

The combustion chamber raises compression above stock while remaining manageable; heads can be decked up to .060", though pistons with valve pockets will require re-machining.

Compatible with stock rocker boxes, exhaust systems, and intake manifolds; machined to accept electric or manual compression releases.

Not compatible with '14–'16 FLHTK/FLHTKL, FLHTCUTG Twin-Cooled motors or '17 touring models, and should not be used with pistons that have a pop-up dome.

Must use the included valve cover gasket kit with stock rocker covers, and the manufacturer's rocker boxes if compression releases are used. Made in the USA. 🇺🇸
