Ferrea Chevy SB 1.94in 11/32in 4.91in 0.25in 10 Deg S-Flo Stk 6000 Series Intake Valve - Set of 8

These Ferrea 6000 Series intake valves feature a 1.94-inch head diameter and a 4.91-inch overall length, designed for Chevy small-block engines. The 10-degree S-Flo seat angle is a key design element, helping to improve airflow into the combustion chamber by reducing turbulence. This specific design choice is important for engines looking to optimize performance, especially when rebuilding the top end.

Constructed from high-grade stainless steel, these valves are built to withstand the heat and stress of continuous operation. The 11/32-inch stem diameter is a standard size for many Chevy SB applications, ensuring compatibility with a wide range of valve guides and related components. Each valve in this set of eight is well-made, ready to handle the demands of performance builds or reliable daily drivers.

When installing these valves, ensure your valve guides are in good condition and properly sized for the 0.25-inch tip length. Proper installation is crucial for achieving the intended airflow improvements and long-term durability. This set is a solid option for anyone working on their Chevy SB engine and looking for reliable intake valve replacements.
