Ferrea Chevrolet BB 2.3in 11/32in 5.421in 12 Deg S-Flo +.200 Competition Plus Int Valve - Set of 8

This is a set of eight Ferrea Competition Plus intake valves, specifically made for Chevrolet Big Block engines. These valves are designed to be a direct replacement for your stock intake valves, but with some key improvements for better engine performance. They measure 2.3 inches in diameter and have a 11/32 inch stem, with an overall length of 5.421 inches. The +.200 designation means these are oversize valves, intended to be used when the valve seat has been enlarged or reconditioned to accept a larger valve, which can help improve airflow into the cylinder.

Ferrea uses strong, well-built materials for their Competition Plus line, aiming for durability and reliable performance under demanding conditions. The S-Flo design is a specific feature Ferrea uses to help improve airflow characteristics into the combustion chamber. These valves are built to handle the stresses of a performance-oriented engine build, offering a solid option for those looking to get more out of their Chevrolet Big Block.

When rebuilding or upgrading the top end of your Chevrolet Big Block, using quality valves like these can make a notable difference in how your engine breathes. Ensure your machine shop is aware these are +.200 oversize valves so they can properly prepare the cylinder heads for installation.
