GSC Exhaust Valve 36mm +1mm (Honda K-Series DOHC VTEC) GSC2044-01

GSC Exhaust Valve – Honda K-Series VTEC – 36mm +1mm Oversize – Single – GSC2044-01

Designed for high-RPM Honda builds with enhanced flow and durability

This single +1mm oversize 36mm exhaust valve from GSC Power Division is precision-engineered for Honda K-Series DOHC VTEC engines. With a 5.5mm stem and an overall length of 108.80mm, it’s built to withstand extreme heat and high RPM while maintaining consistent performance.

GSC’s valve line was developed using advanced 3D design and simulation software to optimize strength and airflow. Each prototype is flow-tested in its intended application to ensure maximum efficiency. The result is a high-performance valve with reduced face distortion—delivering better sealing under pressure and reliable operation over time.

Key Features:

• Swirl-polished head improves airflow across the valve surface
• Backcut design reduces weight for better RPM response and compatibility with aggressive cam profiles
• Micro-polished stem minimizes 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)
