Utilizing cutting-edge 3D design and simulation software, we engineered a stronger, more efficient valve head design. Through rigorous flow testing in specific applications, we have achieved the highest flow rates in the market. Our materials minimize valve distortion, ensuring superior sealing under extreme conditions and consistent performance over time. GSC Power-Division's new valves are poised to set the benchmark for sport compact performance valves.\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eAPPLICATIONS\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eToyota 3STGE\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSwirl polished heads for smoother air flow over the valve\u003c\/li\u003e\n\u003cli\u003eBack cut to reduce valve weight for higher RPM, higher boost pressure, and allow for more aggressive cam profiles without increasing valve spring seat pressures\u003c\/li\u003e\n\u003cli\u003eValve stems are micro-polished to allow for less oil retention on the stem, which creates less drag on the stem to guide for a smoother motion\u003c\/li\u003e\n\u003cli\u003eIntake valves are a modified 21-4n stainless and exhausts are a modified 23-8n stainless material for high heat capacity while maintaining longevity\u003c\/li\u003e\n\u003cli\u003eValve tips are either hardened or have a satellite wafer tip fused so that the tip is within 5 Rockwell C of the rocker or valve tappet for extended life and less wear\u003c\/li\u003e\n\u003cli\u003eValve tip lengths - we have taken extra time to adjust tip heights on the applications to require less tipping of the valve, to maintain proper tip height for proper valve train geometry, and to cut down on install times when setting valve lash\u003c\/li\u003e\n\u003cli\u003eWe have also adjusted the keeper groove to properly balance intake and exhaust spring pressures to reduce the use of valve spring shims and maximize performance from our spring and retainer kits\u003c\/li\u003e\n\u003cli\u003eValves will work with an OEM keeper\/lock or, when available, our upgraded keeper\/lock.
