Ferrea Chevrolet BB 1.88in 11/32in 5.471in 15 Deg S-Flo +.150 6000 Series Exhaust Valve - Set of 8

This set includes eight Ferrea 6000 Series exhaust valves, specifically designed for Chevrolet Big Block engines. Each valve features a 1.88-inch head diameter and a 5.471-inch overall length, with a 15-degree S-Flo design. The +.150-inch stem height is a notable detail for builders looking to achieve specific valve train geometry.

These valves are constructed from Ferrea's 6000 Series alloy, a well-built material known for its strength and durability under high temperatures. The S-Flo design helps improve airflow by reducing turbulence as the air-fuel mixture enters the cylinder, which can contribute to improved engine performance. The 11/32-inch stem diameter is standard for many performance applications, ensuring compatibility with a wide range of valve guides and spring setups.

When rebuilding or upgrading your Chevrolet Big Block's top end, these valves offer a solid option for those seeking reliable components. Ensure you consult your engine build specifications to confirm these dimensions are correct for your application.
