About this part

Product Details

If you're rebuilding a Chrysler 361-383 engine, especially for racing applications under 8000 RPM, these Manley Race Flo exhaust valves are a solid option. They're designed to handle the demands of bracket, drag, and oval track racing, offering improved durability and airflow compared to stock components.

Each valve is made from high-quality stainless steel, chosen for its strength and resistance to heat. The stems are chrome-plated and feature hard tips to reduce wear over time, which is crucial for longevity in a performance engine. Manley also swirl polishes the under-head areas and fully machines the combustion faces. This attention to detail helps optimize airflow into the cylinder and can contribute to better combustion efficiency. These are specifically recommended for exhaust use in alcohol-fueled engines, where they offer reliable performance.

This set includes eight exhaust valves, each with a 1.810-inch head diameter and a 4.908-inch overall length. They are a Race Flo style, which is a specific shape designed to suit certain racing engine configurations.
