Manley Big Block Chevrolet Street Flo 1.880 Head Dia Exhaust Valves

Manley Performance is a well-known name for building solid engine components, and their Street Series valves are a great example of that. If you're looking to improve the performance of a stock or lightly modified Big Block Chevrolet engine, these Street Flo exhaust valves are a solid option. They are made from high-quality stainless steel, which means they'll hold up well over time.

These valves have chrome stems and hard tips, adding to their durability and resistance to wear, even in engines that see regular use. The areas under the head have been swirl polished, and the combustion faces are fully machined. This attention to detail helps improve airflow and makes your combustion process more efficient. The Street Flo shape is designed to work well in these applications, helping you get the most out of your engine.
