About this part

Product Details

Manley Performance is well-known for making strong internal engine components for racing applications. If you're rebuilding the top end of your 1997-2004 Chevrolet Corvette, these Race Master SS intake valves are a solid choice. They feature a 2.080-inch head diameter, designed to help your engine breathe better, especially if you're pushing it beyond 8000 RPM.

These valves are built from stainless steel, which gives them good durability for engines that see a lot of use. The stems are chromed and have hard tips, adding to their wear resistance over time. Manley also swirl-polished the areas under the head and fully machined the combustion faces. This attention to detail helps optimize airflow into the cylinder, which can make a difference in how efficiently your engine burns fuel.

This set includes eight intake valves, enough for a typical V8 engine. They are also recommended for alcohol-fueled engines, indicating their robust construction for demanding conditions.
