S&S Cycle 89cc Super Stock Cylinder Head Kit

For those seeking to enhance their 2006-2016 Harley-Davidson engines, S&S Super Stock Cylinder Heads present a seamless upgrade. Appropriate for standard displacement engines, these heads excel when paired with bigger stroker or big bore engines that reach up to 110 inches. Sporting an 89cc combustion chamber, they offer a higher than average compression ratio without compromising manageability, ideal for heavy-duty touring bikes. They come ready for S&S electric or manual compression releases, ensuring adaptability for any rider's needs. The heads feature sizeable 2.000" intake and 1.605" exhaust valves, optimizing port velocity and air supply to cater to larger engines, boosting their performance capabilities. S&S Super Stock Cylinder Heads offer 264 cfm of airflow, a sizable improvement over the standard 182 cfm, enhancing the overall responsiveness and power. This performance gain is backed by high-performance valve springs designed to accommodate camshafts with lifts up to .650". Complete with a wrinkle black powder coat finish, these heads integrate aesthetically with stock engine parts and are compatible with stock rocker boxes, exhausts, and intake manifolds, making for an impactful yet straightforward enhancement to your ride.

Features:

Black powder-coat finish
89cc
Compatible with stock rocker boxes, exhaust, and intake manifolds
Includes 4 long headbolts for installation
Stock rocker boxes will not work if S&S Cycle electric compression releases are used
Must use the included valve cover gasket kit with stock rocker covers
2.000" intake & 1.605" exhaust valves
Increases flow rate to 264cfm (compared to 182cfm for stock heads)

Note: Super Stock heads will not work with S&S compression releases in a late model twin cam that has HD® ACR's already installed. S&S compression releases are controlled by a starter relay but the stock HD ACRs are controlled by the ECM and they do not work together properly. Damage will be caused to the heads and engine if customer or dealer tries to tie into the HD® wiring.
