Ferrea Chevy SB 1.625in 11/32in 5.01in 12 Deg S-Flo +.100 6000 Series Exhaust Valve - Set of 8

Ferrea is known for making high-performance valvetrain components, and these 6000 Series exhaust valves are a prime example. If you're rebuilding the top end of a Chevy small block engine, these valves are built to handle the demands of performance applications. They are designed to be a direct replacement for your stock exhaust valves, but with improved materials and construction.

These particular valves feature a 1.625-inch head diameter and a 11/32-inch stem, with an overall length of 5.01 inches. They are +.100 inches longer than stock, which can be beneficial for certain camshaft profiles or cylinder head modifications. The S-Flo design helps improve airflow into the combustion chamber, and the 12-degree seat angle is a common specification for many performance builds. The 6000 Series is a popular choice for builders looking for a well-built valve that offers a good balance of performance and durability.

When installing these, ensure your valve guides are in good condition and properly sized for the 11/32-inch stems. It's also a good idea to check your valve spring pressures to make sure they are compatible with the valve weight and intended operating RPM. This set includes eight valves, enough for a complete V8 engine.
