Engineered for Performance and Longevity
GSC’s intake valves are developed using advanced 3D modeling and simulation software to achieve a stronger, higher-flowing head design. Each prototype is tested in its intended engine platform to ensure maximum efficiency and minimal distortion under high heat and pressure. This results in better sealing and consistent performance throughout the valve’s service life.
Key Features:
- Swirl-polished heads enhance airflow and valve aerodynamics
- Backcut design reduces weight for improved RPM capability
- Micro-polished stems minimize oil drag and improve guide movement
- Constructed from modified 21-4n stainless steel for strength and heat resistance
- Stellite-tipped or hardened valve ends for extended wear protection
- Optimized tip height for better geometry and faster lash setup
- Balanced keeper groove to reduce spring shims and maximize kit performance
- Compatible with OEM or upgraded keepers/locks (reuse not recommended for performance builds)
