Ferrea Ford FE 352/390/427/428 2.2in 11/32in 5.45in 12 Deg S-Flo 6000 Series Intake Valve - Set of 8

These Ferrea 6000 Series intake valves feature a 2.2-inch face diameter and are designed for Ford FE engines like the 352, 390, 427, and 428. The 11/32-inch stem diameter and 5.45-inch overall length are specific dimensions to ensure proper fitment within the cylinder head and valve train geometry. The 12-degree S-Flo design is intended to improve airflow into the combustion chamber.

Constructed from high-grade stainless steel, these valves are built to withstand the heat and stress of engine operation. The S-Flo (Swirl-Flo) feature is a unique design element that Ferrea uses to promote better air-fuel mixture swirl as it enters the cylinder, which can contribute to more efficient combustion. This set includes eight intake valves, enough for a complete V8 engine rebuild or upgrade.

When rebuilding or modifying your Ford FE engine, using valves that are properly sized and designed for improved flow can make a notable difference in performance. These Ferrea valves are a solid option for those looking to optimize their engine's breathing capabilities.
