GSC Exhaust Valve 36mm +1mm - Set of 8 (Honda K-Series DOHC VTEC) GSC2044-8

GSC Exhaust Valve Set – Honda K-Series VTEC – 36mm +1mm Oversize – Set of 8 – GSC2044-8

Built for high-RPM Honda performance with optimized flow and long-term durability

This set of eight +1mm oversize 36mm exhaust valves from GSC Power Division is precision-engineered for Honda K-Series DOHC VTEC engines. Each valve features a 5.5mm stem and measures 108.80mm in overall length, designed to handle extreme heat and high RPM while maintaining consistent performance.

GSC developed this valve series using advanced 3D modeling and simulation tools to enhance strength and airflow. Each prototype is flow-tested in its intended engine platform to ensure top-tier performance. The result is a high-efficiency valve with reduced face distortion—delivering better sealing under pressure and reliable operation over time.

Key Features:

• Swirl-polished heads improve airflow across the valve surface
• Backcut design reduces weight for better RPM response and compatibility with aggressive cam profiles
• Micro-polished stems reduce oil retention and drag for smoother movement
• Exhaust valves made from modified 23-8n stainless for superior heat resistance and long-term reliability
• Valve tips are hardened or fused with stelite wafers for extended wear and durability
• Tip heights are optimized to reduce setup time and maintain proper valvetrain geometry
• Keeper grooves are refined to balance spring pressures and reduce the need for shims
• Compatible with OEM or upgraded keepers/locks (reuse of old locks not recommended for performance builds)
