This listing is for a single Ferrea 5000 Series exhaust valve, specifically designed for Chevrolet Big Block engines. You'll receive one exhaust valve with a 1.88-inch head diameter, a 3/8-inch stem, and a length of 5.375 inches. It features a flat head with a 9-degree Flo profile, intended to help improve exhaust gas flow out of the cylinder.

Ferrea's 5000 Series valves are a solid option for many performance builds. They are constructed from durable materials to handle the stresses of combustion. The flat head design with the 9-degree Flo profile is a notable change from standard valve designs, aiming for better volumetric efficiency in the exhaust port. This valve is intended for the driver's side (D/S) application, meaning it's a specific piece for a particular position on the engine.
