If you're rebuilding the top end of your Chevy small block engine, especially for performance applications, you'll want intake valves that can handle the demands. These Ferrea 6000 Series intake valves are built for that purpose. They feature a 2.1-inch head diameter and a 11/32-inch stem, designed to fit a variety of popular cylinder heads for Chevy SB applications.

Ferrea uses high-quality steel for these valves, ensuring they can withstand the heat and stress of combustion. The S-Flo design with a 12-degree seat angle helps improve airflow into the cylinder, which can contribute to better engine performance. This set includes eight valves, and they are +.200 inches longer than stock, which is important to consider when selecting valve springs and retainers to ensure proper geometry and clearance.

When installing these, pay close attention to the valve spring installed height to ensure correct pressure and valve train stability. Ferrea is well-known for making solid engine components, and these valves are a popular choice for builders looking for reliable performance upgrades.
