This set includes eight Ferrea Competition Plus intake valves, each measuring 2.1 inches across the head, with an 11/32-inch stem diameter and a 5.3-inch overall length. These valves are designed for Chevy small-block engines and feature Ferrea's S-Flo design with a 12-degree seat angle, intended to improve airflow into the combustion chamber.

Ferrea uses high-quality materials to build these valves, aiming for durability and performance in demanding engine builds. The Competition Plus series is known for its robust construction, suitable for engines that see regular track use or high-performance street applications. The specific dimensions and S-Flo design are engineered to work with many popular cylinder head porting configurations for Chevy SB engines, helping to optimize the intake charge.
