Leveraging cutting-edge 3D design and simulation software, we meticulously engineered valve heads that are not only stronger but also optimize airflow. Each prototype valve head undergoes rigorous flow testing tailored to its specific application, ensuring we offer the most efficient valve heads on the market today. Our choice of materials has resulted in minimal valve distortion at the sealing face, surpassing all tested designs. This reduced distortion equates to superior sealing capabilities under extreme conditions and unwavering performance throughout the valve's lifespan. GSC Power Division's innovative valves are poised to set a new industry standard for sport-compact performance valves.\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNOTE:\u003c\/strong\u003e \u003cstrong\u003e\u003cem\u003e2014+ Model Fitment ONLY\u003c\/em\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eAPPLICATIONS\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBRZ\/FRS FA20 \u003c\/strong\u003e(2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021)\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 stelite 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.
