GSC Power-Division already has a line of high quality valves and is now introducing a Super Alloy Exhaust valve that is designed for engines that is to be used under extreme conditions. With the new technology in manufacturing and metallurgy GSC Power-Division designed the valves with blends of Super Alloys that are able to handle an incredible amount of heat up to 2000F and power levels to keep up with the high horsepower engines being built in today's racing communities. Every Super Alloy valve has chrome polished stems for a smooth and durable finish to ensure a long life and added lubricity. For maximum lubricity it is recommended to pair these with the GSC manganese bronze valve guides. Not sparing any quality, the heads of the GSC Super Alloy valves are dished for weight saving as the swirl polished and back cut heads will allow for a better air flow.
