About this part

Product Details

If you're rebuilding the top end of your 1997-2004 Chevrolet Corvette, especially for racing applications under 8000 RPM, these Manley Race Flo intake valves are a solid option. They're built with durability and airflow in mind, which is crucial when you're pushing an engine hard on the track.

These valves are made from stainless steel, which is a strong material that holds up well over time. The stems are chromed and have hard tips, adding extra wear resistance where it counts. Manley also swirl polishes the areas under the head and fully machines the combustion faces. This work helps smooth out airflow into the cylinder, making the most of every bit of fuel and air you're feeding the engine.

With a 2.000-inch head diameter and a .3133-inch stem diameter, these valves are designed to fit specific LS-1, LS-2, and LS-6 cylinder heads. They are also recommended for exhaust valves in alcohol-fueled engines, showing their resilience in demanding conditions.
