GSC flow tests prototype valve heads in the specific applications to ensure the highest flowing valve head available on the market today. With the materials used, GSC offers less valve distortion at the face than any of the tested designs. Less distortion allows for better sealing under extreme conditions and more consistent performance throughout the life of the valve.\u003cbr\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\u003eValves will work with an OEM keeper\/lock or, when available, our upgraded keeper\/lock.

The GSC2056-01, GSC2056-12 valve protrusion has been shortened by .15mm to reduce the need to tip the valves on cylinder heads that are receiving a valve job.
