Ferrea Chevrolet BB 2.25in 11/32in 5.471in 12 Deg S-Flo +.250 Competition Plus Int Valve - Set of 8

Ferrea is well-known for making high-performance engine components, and these Competition Plus intake valves are a prime example of their work. Designed for Chevrolet Big Block engines, this set of eight valves is built to handle demanding conditions. They feature a 2.25-inch head diameter and a 11/32-inch stem, with an overall length of 5.471 inches. The 12-degree S-Flo design helps improve airflow into the combustion chamber, and the +.250-inch length is useful for specific porting or piston-to-valve clearance setups.

These valves are constructed from durable materials to ensure they can withstand the heat and stress of high-performance operation. The S-Flo technology is a notable design feature that Ferrea uses to optimize gas flow, which can contribute to improved engine breathing and power output. If you're rebuilding or modifying a Chevrolet Big Block, these valves are a solid option for enhancing the engine's top end.
