Technical Specifications
- Part Number: GSC2124-8
- Oversized Head: +1mm (36mm)
- Stem Diameter: 5.5mm
- Overall Length: 103.25mm
Advanced Design for Flow, Strength, and Longevity
Crafted using advanced 3D modeling and simulation software, GSC’s intake valves feature a reinforced head profile and optimized flow dynamics. Prototype testing ensures peak performance in FA20 applications, while reduced face distortion improves sealing under extreme conditions for consistent results over time.
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)
