Ferrea Chevrolet BB 2.325in 3/8in 5.421in 12 Deg S-Flo +.200 Competition Plus Intake Valve- Set of 8

These Ferrea Competition Plus intake valves are made from a high-strength, high-temperature alloy, specifically chosen for demanding engine builds. Each valve measures 2.325 inches in diameter and 5.421 inches in length, with a 3/8 inch stem. They are designed to be +.200 inches oversized, which is a notable change from stock dimensions, allowing for improved airflow into the combustion chamber.

The S-Flo design features a unique undercut stem and a specialized swirl-polished face. This isn't just for looks; it helps reduce valve shrouding and promotes better air-fuel mixture motion within the cylinder. The 12-degree valve seat angle is also a performance-oriented feature, contributing to a more efficient seal and improved flow characteristics. These valves are well-built for engines that need to perform under pressure, like those found in racing or high-performance street applications.

This set includes eight intake valves, enough for a typical V8 engine. When rebuilding or modifying your Chevrolet big block engine, using valves like these can make a significant difference in overall performance and reliability.
