79 cc Super Stock® Cylinder Heads

79 cc Super Stock® Cylinder Heads

Heads are fully assembled with springs and valves

Designed for stock 88" to 103" engines or slightly modified engines up to 110"

Moderately sized 1.940" intake and 1.575" exhaust valves maintain port velocity in smaller displacement engines for good low and midrange response

S&S® High performance valve springs allow the installation of camshafts with up to .650" lift

Combustion chamber provides a significantly higher than stock, but still manageable compression ratio

Heads can be decked up to .060" to increase compression, but will require piston valve pockets to be re-machined

Compatible with stock rocker boxes, exhaust, and intake manifolds

Machined for S&S® electric or manual compression releases

Made in the USA

Should not be used with any piston having a pop up dome.

Not compatible with '14-'16 FLHTK/FLHTKL, FLHTCUTG Twin-Cooled motors or '17 touring models.

Must use the included S&S valve cover gasket kit with stock rocker covers.

Must use S&S rocker boxes if S&S compression releases are used.
