Designed for Flow, Strength, and Reliability

Using advanced 3D modeling and simulation tools, GSC developed a high-flow valve head with reduced face distortion for better sealing under extreme conditions. Prototype testing ensures optimal performance in FA20 applications, with consistent results throughout the valve’s lifespan.

Key Features:

  • Swirl-polished heads improve intake flow efficiency
  • Backcut design reduces weight for higher RPM and boost
  • Micro-polished stems minimize oil drag and enhance motion
  • Made from modified 21-4n stainless for heat resistance and longevity
  • Hardened or stelite-tipped 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)
