Engineered for Flow, Strength, and Longevity
Developed using advanced 3D modeling and simulation tools, GSC’s intake valves feature a stronger head profile and improved flow characteristics. Prototype testing ensures maximum performance in FA20 applications, while reduced face distortion improves sealing under extreme conditions.
Key Features:
- Swirl-polished heads for smoother airflow
- Backcut design reduces weight for higher RPM and boost
- Micro-polished stems minimize oil drag and improve motion
- Made from modified 21-4n stainless for heat resistance and longevity
- Hardened or stelite-tipped valve ends for reduced wear
- 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)
