This set includes eight Ferrea Competition Plus exhaust valves, ready to go into your Chevrolet small block engine. Each valve features a 1.6-inch head diameter and a 5/16-inch stem, measuring 5.160 inches in overall length. These are designed as a +.200 inch over standard length, which can be useful when rebuilding or modifying your cylinder heads to achieve specific valve train geometry.

Ferrea builds these valves with their S-Flo (Swirl-Flo) design, which helps improve airflow into the cylinder by creating a better swirl pattern. The valves are made from a strong, high-quality steel alloy that's built to handle the heat and stress of exhaust service. The 14-degree seat angle is a common specification for many performance cylinder heads, ensuring a good seal.

If you're rebuilding the top end of your Chevrolet small block and looking for reliable exhaust valves, this set from Ferrea is a solid option. They are well-made and designed for improved performance and durability in demanding engine conditions.
