Hey to all you guys and girls on lancershop! If you have ever wondered about how this website is and how it will treat you as a customer .... Well they are pretty good compared to a buach of other sites out there! Selection of parts is fantastic just need to keep your parts updated on which ones are still continued and which ones are not I don't like looking at things I can't get haha . I have ordered parts from them before and I did not have a problem. They got to my house before the eta which was impressive to me because the parts were coming from different warehouses across the country and from previous experiences with other sites that can be a pain in the butt! Now..... Only one little thing that isn't even a really big deal especially since I had somsomeo assist me right away and didn't leave me clueless..! I ordered rotors and they haven't got here when they were supposed to. But it was around the holidays so I should be prepared for any kind of delay. But hey I had a wonderful girl I.m. me and everything was straightforward and no bull crap and we got everything figured out. :) lancershop is a site I will be using in the future for sure!

GSC Chrome Polished Exhaust Valve - 30mm Head (+1mm) - EVO X

Product Description

When creating our 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 applications 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. GSC Power-Division's new valves are sure to become the industries standard for sport compact performance valves.

Valve Features

    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.

    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 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.

    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 applications do to material grooving.
