GSC Intake Valve Set – Honda B-Series VTEC – 33mm STD – Set of 8 – GSC2032-8
Engineered for high-performance Honda valvetrain buildsThis set of eight standard-size 33mm intake valves from GSC Power Division is designed for Honda B-Series DOHC VTEC engines. Each valve features a 5.5mm stem diameter and measures 102.60mm in overall length, delivering consistent airflow and reliable sealing under high-RPM, high-heat conditions.
Developed using advanced 3D modeling and simulation software, GSC’s valve heads are optimized for strength and flow. Every prototype is flow-tested in its intended application to ensure top-tier performance. The result is a high-flow valve head with reduced face distortion—providing better sealing and long-term durability in demanding environments.
Key Features:
- Swirl-polished heads promote smoother airflow across the valve surface
- Back-cut design reduces weight for improved RPM response and compatibility with aggressive cam profiles
- Micro-polished stems minimize oil retention and drag for smoother valve movement
- Intake valves crafted from modified 21-4n stainless for heat resistance and extended lifespan
- Valve tips are either hardened or fused with stelite wafers for long-lasting wear resistance
- Tip heights are optimized to reduce setup time and maintain proper valvetrain geometry
- Keeper grooves are precision-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)
