Manley Chevrolet Small Block Exhaust Valve Kit - 1.625in Head Dia. 5.065in O/A Length, 0.3415in Stem

This kit gives you the exhaust valves you need for your Chevrolet Small Block engine build. These are Manley's Race Series valves, built for engines that see a lot of action, like those in bracket, drag, or oval track racing, especially when they're running up to 8000 RPM. They're made from a strong stainless steel that holds up well over time, and the stems are chromed with hard tips to resist wear, which is important for keeping things running smoothly.

What's really neat about these valves is how they're finished. The areas under the head are swirl polished, and the combustion faces are fully machined. This helps improve how air flows into the cylinder and how efficiently the fuel burns. Manley also offers different shapes, like the Race Master straight stem or the Race Flo, so you can pick what works best for your specific engine setup. They're even a recommended choice for alcohol-fueled engines, showing they can handle tough conditions.
