Manley Chevrolet Small Block Exhaust Valve Kit - 1.600in Head Dia. 5.240in O/A Length, 0.3110in Stem

If you're rebuilding the top end of your Chevrolet Small Block engine and need a solid set of exhaust valves, this Manley Race Series kit is a great option. These are built for engines that see a lot of action, especially those running up to 8000 RPM, making them a popular choice for drag racing or oval track builds. They're also recommended for alcohol-fueled engines, which can be tough on components.

Manley makes these valves from a strong stainless steel that holds up well to the heat and stress of combustion. The under-head area is swirl polished to help smooth out airflow into the cylinder, and the combustion face is fully machined to keep things efficient. You'll also notice they have chrome stems and hard tips, which adds to their durability and resistance to wear, especially important for the exhaust side.

This kit includes exhaust valves with a 1.600-inch head diameter and a 5.240-inch overall length, featuring a 0.3110-inch stem. Make sure these dimensions match your cylinder head and valve guide setup before ordering.
