Manley thru 08 Chrysler Hemi 5.7L w/ Triple Groove 1.555in Race Master Exhaust Valves (Set of 8)

If you're rebuilding the top end of your 2005-2008 Chrysler 300 with a 5.7L Hemi, these Manley Race Master exhaust valves are a solid choice. They're built for engines that see a lot of action, especially those running under 8000 RPM, like in bracket racing or drag strip applications. These valves are designed to handle the heat and stress of performance engines.

Manley makes these valves from a strong stainless steel, which helps them last a long time. The stems are chrome-plated and the tips are hardened for extra wear resistance, meaning they'll hold up better over many cycles. They've also been swirl polished under the head and fully machined on the faces to help air move more freely through the engine, which can make a difference in how efficiently it runs. These are the Race Master style, which means they have a straight stem.

These valves are also recommended for use in alcohol-fueled engines, where exhaust valves can face particularly tough conditions. If you're building a performance Hemi and need reliable exhaust valves, these are a well-made option.
