Ferrea Chevrolet SB 1.6in 11/32in 5.56in 12 Deg S-Flo +.600 Super Alloy Exhaust Valve - Set of 8

If you're rebuilding the top end of your Chevrolet Small Block engine, especially for performance applications, you need exhaust valves that can handle the heat and pressure. These Ferrea S-Flo valves are built for that kind of work, designed to keep your engine running strong under demanding conditions.

Ferrea uses a special Super Alloy material for these exhaust valves, which is known for its ability to resist high temperatures and wear. The S-Flo design features a special undercut stem and a swirl-polished face, which helps improve airflow into the cylinder and keeps the valve seating cleaner. With a 1.6-inch head diameter, 11/32-inch stem, and a length of 5.56 inches, these valves are a popular choice for many performance Small Block builds. They are also +.600 inches longer than stock, which is important to consider when setting up your valve train geometry.

This set includes eight valves, enough for a full V8 engine. When installing, pay close attention to your valve spring installed height and any necessary pushrod length adjustments due to the longer valve stem.
