About this part

Product Details

Starting with a 1.920 inch diameter, these Manley Race Master intake valves are built for serious performance in your Dodge Viper V-10. They're constructed from high-quality stainless steel, which means they're going to hold up well under the heat and stress of racing applications, especially if you're running alcohol in your engine. The stems are chrome-plated and the tips are hardened, adding even more wear resistance for improved longevity.

You'll also notice the swirl-polished under-head areas and fully machined combustion faces. This design work is all about optimizing airflow into the cylinder and improving combustion efficiency, which can make a real difference when you're pushing your engine hard, particularly under 8000 RPM. Manley offers these in a Race Master straight stem design, which is what you're looking at here, to fit specific engine builds.

This set includes 10 valves, ready for your V-10 engine rebuild. If you're working on a high-performance engine that sees regular track time or bracket racing, these are a solid option to consider for improved reliability and performance.
