Ferrea Chevrolet BB 1.92in 11/32in 5.45in 14 Deg S-Flo Competition Plus Exhaust Valve - Set of 8

The Ferrea F1215P Competition Plus is an exhaust valve designed for Chevrolet Big Block engines. It features a 1.920-inch diameter head, a 0.3415-inch stem diameter, and an overall length of 5.450 inches.

Constructed from special aerospace-quality alloys like EV8-Z18, these valves offer high tensile strength. Ferrea utilizes an exclusive two-step slow forging process to ensure proper grain flow and minimize material structure damage. The valves are then heat-treated and stress-relieved over a 48-hour period for molecular integrity, and feature avionics-quality hard chrome with a specially applied hard tip.
