Ferrea Chevrolet LS3 2.165in 4.9in 12 Deg S-Flo B/C 30 Deg Rad Grv 6000 Series Int Valve - Set of 8

Ferrea is well-known for making high-performance valvetrain components, and these 6000 Series intake valves are a prime example of their work for Chevrolet LS3 engines. If you're rebuilding or upgrading your LS3's top end, these valves are designed to handle the demands of performance builds. They feature Ferrea's S-Flo (Swirl Flow) design, which helps improve airflow into the combustion chamber, and a 30-degree radiused groove for better sealing.

These valves measure 2.165 inches in diameter and have a 4.9-inch overall length, making them a direct fit for many LS3 applications. The 12-degree valve face angle is standard for many LS engines. They are constructed from a strong, durable material suitable for high-performance use, ensuring they can withstand the heat and stress of an engine working hard. This set includes eight valves, enough for a complete set of intake valves for your LS3.
