Ferrea Chevy SB 1.625in 11/32in 5.06in 20 Deg Semi Tulip S-Flo +150 6000 Series Exh Valve - Set of 8

Ferrea is well-known for making high-performance engine components, and these 6000 Series exhaust valves are a prime example. If you're working on a Chevy small-block engine and need to replace or upgrade your exhaust valves, this set is built to handle the demands of performance builds. They feature a semi-tulip head design with a 20-degree back cut, which helps improve airflow into the combustion chamber.

These valves are constructed from a strong, high-quality steel alloy designed for durability in demanding engine conditions. They measure 1.625 inches across the head and have a 5.06-inch overall length with a 0.343-inch (11/32 inch) stem diameter, making them a direct fit for many Chevy SB applications. The +150 rating indicates they are designed to handle increased spring pressures, common in performance camshaft applications.

This set includes eight valves, enough for a complete V8 engine. When installing, ensure you have the correct valve guides and seals to match the stem diameter for optimal performance and longevity.
