About this part

Product Details

If you're rebuilding the top end of a 1968-1973 Dodge 5.6L small block engine, these Manley Race Series exhaust valves are a solid option. They're built for engines that see a lot of action, especially those running up to 8000 RPM, making them a good choice for bracket, drag, or oval track use.

These exhaust valves are made from a high-quality stainless steel that's tough enough to handle the heat and stress of performance use. The stems are chromed for better wear resistance, and the area under the head is swirl polished to help improve airflow into the cylinder. The combustion face is also fully machined, which can help with how efficiently the fuel burns.

Manley also notes that these are a recommended exhaust valve for engines running on alcohol fuel, which can be a more demanding environment. You'll get a set of 8 valves, enough for a full V8 engine rebuild.
