Ferrea Chevy SB 1.94in 11/32in 5.01in 0.25in 12 Deg +.100 6000 Series Int Valve - Single (D/S Only)

This Ferrea 6000 Series intake valve is made from high-strength stainless steel, specifically chosen for its durability under high temperatures and pressures found in performance Chevy SB engines. The valve face measures 1.94 inches, which is a common size for improved airflow in many small-block Chevy applications, and it has a total length of 5.01 inches with a 0.25-inch margin for +.100 valve guides. The 11/32-inch stem diameter is standard for many performance builds, ensuring compatibility with a wide range of valve springs and retainers.

Ferrea uses a specialized heat-treating process for their 6000 Series valves, which helps them resist wear and maintain their shape even when subjected to aggressive camshaft profiles and high RPMs. This particular valve is designed for the intake side and features a 12-degree swirl polished face, which helps to promote better fuel-air mixture motion as it enters the cylinder. It's sold individually, so you'll need to order the correct quantity for your engine build.
