GSC Power-Division is expanding its already successful valve line to now include a Super Alloy Exhaust valve. The new Super Alloy Exhaust valves were designed for engines used in extreme conditions. With advancements in manufacturing technology and metallurgy, GSC Power-Division was able to design a blend of Super Alloys that can handle the immense heat and power levels of today's ultra-high horsepower turbocharged and normally aspirated engines. The GSC Super Alloy exhaust valves are designed to withstand EGT's between 1800-2000F. Each Super Alloy Exhaust valve utilizes chrome polished stems to create a smooth, durable finish for added life and better lubricity especially when paired with GSC manganese bronze valve guides. Strength, heat resistance and performance are engineered into every valve. In addition, head dish is maximized for weight savings while swirl polished and back cut heads promote better air flow without sacrificing durability.
