GSC Exhaust Valve 33mm Standard (Honda B-Series DOHC VTEC) GSC2032-01

GSC Intake Valve – Honda B-Series VTEC – 33mm STD – Single – GSC2032-01

Built for high-performance Honda valvetrain upgrades

This standard-size 33mm intake valve from GSC Power Division is engineered for Honda B-Series DOHC VTEC engines. With a 5.5mm stem diameter and 102.60mm overall length, it’s designed to deliver consistent airflow and reliable sealing under high-stress conditions.

GSC’s valve line was developed using advanced 3D modeling and simulation tools to enhance strength and flow characteristics. Each prototype is flow-tested in its intended application to ensure maximum performance. The result: a high-flow valve head with minimal distortion, offering better sealing and long-term durability in high-heat environments.

Key Features:

• Swirl-polished heads improve airflow across the valve surface
• Back-cut design reduces weight for better RPM response and compatibility with aggressive cam profiles
• Micro-polished stems reduce oil retention and drag for smoother valve movement
• Intake valves made from modified 21-4n stainless for heat resistance and longevity
• Valve tips feature hardened ends or fused stelite wafers for extended wear life
• Optimized tip height reduces setup time and ensures proper valvetrain geometry
• Keeper grooves are tuned 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)
