About this part

Product Details

Ferrea is well-known for making high-performance engine components, and these S-Flo exhaust valves are a prime example of their work. If you're rebuilding the top end of a Chevrolet Small Block engine, these valves are designed to handle the demands of performance builds. They feature a 1.6-inch head diameter and a 5.16-inch overall length, with a 0.250-inch over-length to help with piston-to-valve clearance in modified applications.

These valves are constructed from a super alloy material, which is chosen for its strength and resistance to high temperatures found in performance exhaust ports. The 11/32-inch stem diameter is standard for many performance applications, and the 12-degree S-Flo design helps improve airflow compared to a traditional valve face. This updated design can contribute to better cylinder filling and exhaust scavenging.

This set includes eight valves, enough for a complete V8 engine. When rebuilding an engine, using well-made valves like these from Ferrea is important for ensuring proper sealing and performance for the life of the engine.
