Ferrea Chevy SB 2.1in 11/32in 5.01in 12 Deg S-Flo +.100 Competition Plus Intake 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 for Chevy small-block engines. If you're rebuilding the top end of your engine and looking for valves that can handle more aggressive use, these are a solid option. They measure 2.1 inches across the head and have a 11/32-inch stem, with an overall length of 5.01 inches. This specific set is +.100 inches longer than stock, which can be useful for certain camshaft profiles or cylinder head combinations.

These valves are built with durability and performance in mind. The S-Flo design is intended to improve airflow into the cylinder, which can lead to better combustion and more power. The 12-degree seat angle is a common specification that works well with many cylinder head designs. When you're putting together a performance engine, the details matter, and valves like these are a critical part of ensuring your engine breathes efficiently and reliably.
