Ferrea Chevy SB (Dart Buick Head) 2.1in 11/32in 5.4in 0.25in 12 Deg Flo Comp Plus Int Valve-Set of 8

If you're rebuilding the top end of your Chevy SB engine, especially one fitted with Dart or Buick heads, you'll want to make sure your intake valves can keep up with your performance goals. This set of eight Ferrea Flo Comp Plus intake valves is designed to handle increased airflow demands. The 2.1-inch diameter face is a common upgrade for many performance SB applications, helping to fill the cylinder more effectively.

Ferrea is known for making well-built valvetrain components, and these valves are no exception. They feature a 12-degree swirl polished face, which helps to promote better air-fuel mixture motion as it enters the cylinder. The 11/32-inch stem diameter and 5.4-inch overall length are standard dimensions for many performance SB heads, ensuring a good fit. The 0.25-inch tip length is also a common specification for valve spring retainers.

This set includes eight intake valves, enough for a complete V8 engine. When you're aiming for improved performance from your small block Chevy, reliable valvetrain components like these Ferrea valves are a critical part of the equation.
