GSC Exhaust Valve 35mm Standard (Honda K-Series DOHC VTEC) GSC2042-01

GSC Intake Valve – Honda K-Series VTEC – 35mm STD – Single – GSC2042-01

Engineered for high-flow, high-RPM Honda performance builds

This standard-size 35mm intake valve from GSC Power Division is precision-built for Honda K-Series DOHC VTEC engines. With a 5.5mm stem and an overall length of 108.80mm, it’s designed to deliver exceptional airflow, heat resistance, and long-term reliability in demanding setups.

GSC’s valve line was developed using advanced 3D modeling and simulation tools to optimize strength and flow. Each prototype is tested in its intended application to ensure maximum performance. The result is a high-flow valve with minimal face distortion—providing better sealing under extreme conditions and consistent operation over time.

Key Features:

• Swirl-polished head enhances airflow across the valve surface
• Backcut design reduces weight for improved RPM response and aggressive cam compatibility
• Micro-polished stem minimizes oil retention and drag for smoother movement
• Intake valves made from modified 21-4n stainless for high heat tolerance and extended durability
• Valve tips are hardened or fused with stelite wafers for reduced wear and longer service life
• Tip heights are optimized to reduce setup time and maintain proper valvetrain geometry
• Keeper grooves are refined to balance spring pressures and minimize the need for shims
• Compatible with OEM or upgraded keepers/locks (reuse of old locks not recommended for performance builds)
