About this part

Product Details

When you're rebuilding the top end of your Chrysler Hemi 6.1L, you're getting a set of eight Manley Race Series intake valves. These valves are built from high-quality stainless steel, which is a solid choice for durability under high engine loads. The stems are chrome-plated and feature hard tips, adding extra wear resistance where it counts.

Manley's Race Flo design means these valves have a fully machined combustion face and swirl-polished under-head areas. This helps optimize airflow into the cylinder, which is important for getting the most out of your engine, especially if you're running it up to 8000 RPM. The 2.080-inch head diameter is a specific size for these Hemi applications, designed to work with the factory or aftermarket cylinder heads.

These valves are a well-built option for racers and serious engine builders. They're also recommended for exhaust valves in alcohol-fueled engines, though this set is specifically for intake use. Make sure to check your cylinder head's valve guide and spring compatibility to ensure a smooth installation.
