Ferrea Chevrolet BB 2.3in 11/32in 5.471in 12 Deg S-Flo +.250 6000 Series Intake Valve - Set of 8

These Ferrea 6000 Series intake valves are built with a specific material choice in mind: high-strength stainless steel. This material is chosen for its ability to withstand the heat and stress inside a performance engine, especially for Chevrolet Big Block applications. The valves feature a 2.3-inch head diameter and a 5.471-inch overall length, with a 11/32-inch stem diameter, making them a solid option for rebuilding or upgrading your engine's top end.

The S-Flo design with a 12-degree seat angle is a notable feature that helps improve airflow into the combustion chamber. This design choice can contribute to better cylinder filling and potentially improved engine performance. Each valve is also +.250 inches longer than a standard valve, which is important to consider when setting up your valve train geometry to ensure proper geometry and clearance.

This set includes eight intake valves, enough for a full set of cylinders on a V8 engine. When rebuilding or modifying your Chevrolet Big Block, using well-made valves like these from Ferrea is a key step in ensuring your engine runs reliably and efficiently.
