S&S CYCLE 79 cc Super Stock® Cylinder Heads — Wrinkle Black – 06, 11-17 Dyna, 06-15 CVO, 10-16 Trike, 10-11 Touring, 07-17 Softail

Fully assembled 79 cc Super Stock® cylinder heads include springs and valves and are built for stock 88" to 103" engines, or slightly modified engines up to 110".

Moderately sized 1.940" intake and 1.575" exhaust valves preserve port velocity for strong low- and midrange response, while S&S® high-performance valve springs allow camshafts with up to .650" lift.

The combustion chamber yields a notably higher but manageable compression ratio, and the heads can be decked up to .060" (piston valve pockets must be re-machined when doing so).

These heads are machined for S&S® electric or manual compression releases and are compatible with stock rocker boxes, exhaust, and intake manifolds; you must use the included S&S valve cover gasket kit when retaining stock rocker covers and S&S rocker boxes if S&S compression releases are installed.

Made in the USA. Do not use with any piston that has a pop-up dome. Not compatible with '14-'16 FLHTK/FLHTKL, FLHTCUTG Twin-Cooled motors or '17 touring models. Not for late model twin cam Harley Davidson® ACR's (Atomatic Compression Release) already installed.
