Ferrea 1.91in / 3/8in / 5.4in / 0.225in / S-Flo +.050 Competition Plus Exhaust Valve | 1965 Chevrolet Corvette & 1967 – 1972 Chevrolet Camaro (F2105P) Ferrea Racing

1.91in / 3/8in / 5.4in / 0.225in / S-Flo +.050 Competition Plus Exhaust Valve – Single by Ferrea

To manufacture the valves we use special aerospace quality alloys, including the EV8-Z18, which provides high tensile strength. An exclusive two-step slow forging process ensures proper grain flow and virtually eliminates any damage to the material structure. The valves are then heat-treated and stress-relieved over a 48-hour period, which is the crucial base of our molecular integrity. These valves feature avionics-quality hard chrome along with a specially applied hard tip. Our engineering staff at Ferrea spends countless hours conducting flow bench tests to achieve an optimum balance of flow, velocity and efficiency in the design of these valves. As a result, these valves incorporate smoother radiuses and unique undercuts. These exclusive features are what make the Ferrea Competition Plus Valves unequalled in performance and reliability!

The exhaust valves in the Competition Plus series are manufactured from Ultra High Strength, High Temp Nickel Stainless Steel Alloys. Ferrea first used this material with great success during the development of a very high stress, high temp endurance racing program.
