79 cc Super Stock® Cylinder Heads

Cylinder Heads - 79 cc - Super Stock® - Twin Cam

• 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.
