Ferrea Chevrolet SB 2.055in 5/16in 5.01in 12 Deg Flo Rad Grv +.100 6000 Series Int Valve - Single

These valves are constructed from special aerospace quality alloys, such as EV8-Z18, and undergo a proprietary two-step slow forging process to ensure optimal grain flow and material integrity. They are heat-treated and stress-relieved over a 48-hour period for molecular stability.

The valves feature avionics-quality hard chrome plating and a specially applied hard tip for enhanced durability. Ferrea's engineering team meticulously conducts flow bench tests to balance flow, velocity, and efficiency, incorporating smoother radiuses and unique undercuts for superior performance. The exhaust valves are specifically manufactured from Ultra High Strength, High Temp Nickel Stainless Steel Alloys, offering increased tensile strength, fatigue resistance, and valve seat life at high temperatures.
