GSC Power-Division Performance Intake Valves 37mm (+1mm) for Subaru EJ20/257

Description: When creating the new valve line we set out to create the best performance longest lasting valves available to the aftermarket. Using advanced 3D design and simulation programs we have created a stronger and higher flowing valve head design. We flow test prototype valve heads in the specific Compatible with: to make sure we have the highest flowing valve head available on the market today. With the materials used we have less valve distortion at the face than any of the tested designs. Less distortion allows or better sealing under extreme conditions and more consistent performance threw the life of the valve. Features -Back cut to reduce valve weight for higher rpm, higher boost pressure and allow for more aggressive cam profiles without increasing valve Making Automotive Dreams a Reality Store Home View Our Listings Bookmark Us Contact Us MENU Store Categories Air Intake Brakes & Suspension Clearance Drivetrain Engine & Cooling Exhaust Fabrication Forced Induction Fueling Styling Tuning & Gauges Store Support Store Home View Our Listings Bookmark Us Contact Us Shop by Make Select Your Make...

Features -Back cut to reduce valve weight for higher rpm, higher boost pressure and allow for more aggressive cam profiles without increasing valve spring seat pressures. -Valve stems are micropolished to allow for less oil retention on the stem which creates less drag on the stem to guide for a smoother motion. -Intake valves are a modified 21-4n stainless and Exhausts are a modified 23-8n stainless material for high heat capacity while maintaining longevity. -Valve 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 -Valve tips. We have taken extra time to adjust tip heights on the Compatible with: 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. -We have also adjusted the Keeper grove 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. -Valves will work with an OEM keeper/lock or when available our upgrade keeper/lock. It's not mandatory but it is suggested that any valve lock not be reused on performance Compatible with: do to material grooving. Questions about this item? Click here to contact us!
