Ferrea Chevrolet BB 2.19in 11/32in 5.221in 12 Deg S-Flo Stk 5000 Series Intake Valve - Set of 8

These Ferrea 5000 Series intake valves are built with a specific 12-degree S-Flo angle, a design choice that helps improve airflow into your Chevrolet Big Block engine. Each valve measures 2.19 inches in diameter and has a length of 5.221 inches, with a 11/32 inch stem size, making them a direct replacement for stock applications.

Ferrea uses a high-quality steel alloy for these valves, chosen for its strength and ability to withstand the heat and pressures inside your engine's combustion chamber. The S-Flo design is a notable feature that helps reduce turbulence as the air-fuel mixture enters the cylinder, contributing to a more efficient burn. This set includes eight valves, enough to service a full set of cylinders on most V8 engines.
