Developed using advanced 3D modeling and simulation software, GSC’s intake valve design delivers improved airflow and reduced face distortion for better sealing under high heat. Each valve is flow-tested in VR38-specific applications to ensure maximum performance and durability.
- Enhance airflow across the valve surface
- Reduces weight for better RPM response and boost handling
- Minimize oil retention and reduce drag for smoother movement
- Material: Modified 21-4n stainless steel for intake valves (heat-resistant and long-lasting)
- Hardened or fused with stelite wafer for extended wear resistance
- Reduces tipping and simplifies valve lash setup
- Balances spring pressure to reduce shim use and enhance spring/retainer performance
- Compatibility: Works with OEM or GSC upgraded keeper/lock (new locks recommended for performance builds)
This version features a shortened valve protrusion for heads receiving a valve job. For direct OEM replacement without machining, use GSC2050-01 or GSC2050-12.
