Cylinder Works’ CYL Cylinder Head Kit is engineered for performance upgrades. The shortened valve guides are designed to accommodate high‑lift camshafts, enabling greater torque output and enhanced power delivery. This modification allows the engine to operate at higher lift settings without compromising reliability.
The kit features C630 nickel/aluminum valve seats and guides, which provide a smoother interaction with the valve stem, reducing wear and extending component life. Stock‑shaped ports are retained to maintain high airflow efficiency, while valves, springs, retainers, and lifters are supplied separately to give users full control over their final build.
