S&S CYCLE 79 cc Super Stock® Cylinder Head — Wrinkle Black – 99-06 Touring, 00-06 Softail, 99-06 Dyna

Fully assembled cylinder heads arrive with springs and valves to simplify installation.

Large 1.940" intake and 1.575" exhaust valves maintain port velocity for strong low- and midrange response while allowing excellent airflow for stock and slightly larger engines.

High-performance valve springs allow installation of camshafts with up to .650" lift in most applications; some versions are limited to .585"—verify fitment before installing. 🔧

Heads can be decked up to 0.060" to increase compression; if higher TDC lifts are used or heads are decked, piston valve pockets will require re-machining.

Compatible with stock rocker boxes, exhaust, and intake manifolds unless noted, and machined for compression releases where applicable (compression releases sold separately).

Does not include rocker arm components, intake manifold, or gaskets; should not be used with pistons that have a pop-up dome. High port flow delivers immediate performance and provides headroom for future upgrades. 🇺🇸
