When designing these valves, GSC used advanced 3D design and simulation programs to create a stronger and higher flowing valve head design. Prototypes were used in the specific applications to make sure that they have the highest flowing valve head that is available on the market today. The materials they have used have less valve distortion at the face than any of the tested designs which allow for better sealing under extreme conditions to promote more consistent performance through the life of the valve.
Comes in a set of 8 intake valves.
Here are more key features:
Valve Features:
They 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 their spring and retainer kits.
Valves will work with an OEM keeper/lock or when available their upgraded keeper/lock. It's not mandatory but it is suggested that any valve lock not be reused on performance applications due to material grooving.

My machinist was very pleased with the quality of the valves and they were almost all had nice contact surfaces. He did have to turn a few to correct them. But he said it is very common now days on almost all valves so I would recommend checking the contact surface with the valve seat and have a machinist correct them if they are not perfect. This will make the lapping go much better.
A must when building your motor. Great price and parts.
I decided to go with these valves on my ej205 stroker, since some of my old valves were bent. The packing was awesome. The price is fair, and the attention to detail on each valve is amazing the swirl is perfect.
First-rate material, my machine shop praised the material a lot. Fits perfectly
