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

The 79 cc Super Stock® cylinder head ships fully assembled with springs and valves for straightforward installation. 🔧

Large 1.940" intake and 1.575" exhaust valves maintain port velocity for strong low- and midrange response while supplying enough air for stock and slightly larger engines.

High-performance valve springs allow camshafts with up to .650" lift, and the heads can be decked up to 0.060" to increase compression.

Heads are compatible with stock rocker boxes, exhaust, and intake manifolds and are machined for compression releases (sold separately). 🔩

High port flow gives great performance immediately and preserves headroom for later upgrades; if cams with higher TDC lifts are used or heads are decked, piston valve pockets may require re-machining.

Does not include rocker arm components, intake manifold, or gaskets, and should not be used with any piston having a pop up dome.

Made in the USA.
