Gsc Polished Stainless Intake Valves Fits Subaru Wrx Ej205 Ej255 Sti Ej207 Ej257
Less distortion allows or better sealing under extreme conditions and more consistent performance threw the life of the valve. GSC Power-Division's new valves are sure to become the industries standard for sport compact performance valves. Swirl polished heads for smoother air flow over the valve. 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. Fully nitrated (this includes the 45 which increases valve life and makes a better seal at the valve seat for improved cylinder pressure) also reduces carbon buildup on the backside of the valve. 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. 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.
It's not mandatory but it is suggested that any valve lock not be reused on performance applications do to material grooving. Please message us for a Return Authorization Number before sending anything back to avoid processing delays. Real Street Performance is unlike most "Race Shops".
