Ferrea Chevrolet BB 2.19in 11/32in 5.346in 12 Deg S-Flo +.100 Comp Plus Intake Valve - Set of 8

Ferrea is well-known for making high-performance engine components, and these Comp Plus intake valves are a prime example of their work for Chevrolet big-block engines. If you're rebuilding the top end of your engine and looking for improved airflow and durability, these valves are a solid option.

These intake valves feature a 2.19-inch head diameter, which is larger than stock for many applications, helping to increase airflow into the combustion chamber. The 11/32-inch stem diameter is standard for many performance builds, and the overall length is 5.346 inches. They are designed with a 12-degree S-Flo profile, which is an updated design that helps improve airflow characteristics. The fact that they are +.100 Comp Plus means they are a bit longer than standard, which can be useful for achieving specific compression ratios or valve train geometry in modified engines. They are sold as a set of 8, so you get everything you need for a full set of intake valves.
