S&S CYCLE 79 cc Super Stock® Cylinder Head (Twin Cam) – Pair Upgrade your Twin Cam with the S&S CYCLE 79 cc Super Stock® Cylinder Head. Fully assembled and built in the USA for strong performance across the rpm range—ideal for street riders seeking reliable power and responsive driveability. Key Features Fully assembled with springs and valves for easy installation. Designed for 88"–103" stock motors; ideal for larger stroker/big bore builds up to 110" . Valve sizes for airflow & velocity : 1.940" intake and 1.575" exhaust help maintain port velocity for strong low-to-mid response, while still supporting full-throttle airflow. S&S high-performance valve springs support camshafts up to .650" lift (unless noted). Can be decked up to 0.060" to increase compression. Compatible with stock rocker boxes , intake and exhaust manifolds (unless noted). Machined for compression releases (sold separately). High port flow delivers great performance now and room to grow with future upgrades. Powder-coated wrinkle black aluminum for durability. Notes If using higher TDC-lift cams or decking heads, piston valve pockets may require re-machining. Does not include rocker arm components, intake manifold, or gaskets. Do not use with pistons having a pop-up dome. If using S&S compression releases, use S&S rocker boxes .

Works great with 88" to 103" stock motors, but are ideal for larger stroker or big bore engines up to 110"
Large 1.940" intake and 1.575" exhaust valve maintain port velocity for good low and midrange response, but supply enough air for stock and slightly larger engines to perform to their full potential
S&S® High performance valve springs allow the installation of camshafts with up to .650" lift (unless noted)
Heads can be decked up to 0.060" to increase compression
Compatible with stock rocker boxes, exhaust, and intake manifolds (unless noted)
Heads are machined for compression releases (sold separately)
High port flow gives great performance now, and more later when additional upgrades are done
Made in the USA
If cams with higher TDC lifts are used or if heads are decked, piston valve pockets will require re-machining.
Does not include rocker arm components, intake manifold or gaskets.
Should not be used with any piston having a pop up dome.
