Cylinder Heads - 79 cc - Super Stock® - Twin Cam
Enhance your Twin Cam engine's performance with the S&S Cycle Super Stock Cylinder Heads, part number 106-4277. These heads are fully assembled with springs and valves, ensuring a straightforward installation process. Designed to work seamlessly with stock motors from 88" to 103", they are also ideal for larger stroker or big bore engines up to 110" for improved power output. The large 1.940" intake and 1.575" exhaust valves maintain excellent port velocity, providing strong low and midrange response while supplying enough airflow for both stock and slightly larger engines to reach their full potential.

They can be decked up to 0.060" to increase compression ratios, offering flexibility for tuning and performance upgrades.
