Ferrea Chevy SB 1.6in 11/32 4.960in +.050. Competition Plus Exh Valve - Single (Drop Ship Only)

The Ferrea Racing F1100PQ-1 is an exhaust valve from the Competition Plus series, designed for Small Block Chevy engines. It features a 1.600-inch head diameter, a 11/32-inch valve stem diameter, and a length of 4.960 inches, constructed from stainless steel.

They are manufactured using special aerospace-quality alloys and undergo an exclusive two-step slow forging process for optimal grain flow and material integrity. The valves are heat-treated and stress-relieved over a 48-hour period, and feature avionics-quality hard chrome with a specially applied hard tip. Ferrea's engineering staff conducts extensive flow bench tests to achieve an optimum balance of flow, velocity, and efficiency, resulting in smoother radiuses and unique undercuts for superior performance and reliability.
