Set of 8 Exhaust Valves Standard size for 4B11T EVO 10 by GSC Power-Division

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.

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.

Customized Titanium for my WRX

I’ve been plotting getting a lot of JDC hardware and when the St. Pattys day sale went live I chose to do just that, get some custom (green) titanium hardware! All custom orders are a lead time of 15-20 days mine went a bit longer than I thought it would take but I’m an understanding person and patiently awaited the arrive of my hardware! Needless to say they exceed my expectations and lead me to message Jon through instagram about a custom plate mount for my WRX, and to my surprise he took on the task! This is by far not my last order though JDC I have an active cart going as of now, hoping to get the engine bay caps in the same color(green) very soon! 100 percent happy with my transaction and order! Thanks so much JDC and owner Jon!

Love jdc customs
