Ferrea Chevrolet BB 2.3in 11/32in 5.471in 12 Deg S-Flo +.250 Competition Plus Int Valve - Set of 8

Ferrea is well-known for making strong valvetrain components, and this set of Competition Plus intake valves is a prime example. These valves are built for Chevrolet Big Block engines and are designed to handle the demands of performance builds. They feature a 2.3-inch head diameter and a 5.471-inch overall length, with a 12-degree S-Flo design. The +.250 inch sizing indicates they are oversized by a quarter inch, which is common when rebuilding or upgrading cylinder heads to improve flow and sealing.

These valves are constructed from high-grade steel, chosen for its durability and ability to withstand high temperatures and pressures found in performance engines. The S-Flo design helps improve airflow into the cylinder, contributing to better overall engine performance. The +.250 sizing means they are intended for use in cylinder heads that have been machined to accept larger valves, often part of a performance porting job. This set includes eight valves, enough for a typical V8 engine.
