Engine Pro has been manufacturing various engine components and supplying automotive professionals since 1989, and in this video, Engine Pro president Jesse Jones and product manager Alan Stevenson talk briefly about the company’s different product lines of valves.

For street/strip applications or common naturally-aspirated dirt track or late-model asphalt engine builds, Engine Pro offers its 1000 series valves, which are manufactured from 21-2N high-purity stainless steel.

For serious/maximum effort racing engines, Engine Pro offers its 2000 series valves, which are crafted from 21-4N material, that doubles the nickel content for additional durability and wear resistance. While both the 1000 and 2000 series valves are given a hard chrome finish, the 2000 series valves are further treated with a swirl-polish for a smoother finish.

In applications where engines may seem extended periods of run time, such as in endurance racing or off-shore boat racing, Engine Pro offers its 3000 series Nitro Black cylinder head valves. These are designed specifically for racing applications and receive a five-step liquid nitriding process that uses special salts to smooth the surface of the valves.

The surface treatment results in a 21-percent smoother finish than hard chrome, which provides less valve and guide wear and inhibits carbon buildup on the back of the valves. The nitriding also improves ductility, which means the valves are less likely to break, even after contacting a piston. The 3000 valves also offer greater heat resistance, which makes them a more affordable option for those who might be looking to a more exotic Inconel valve for their application. Additionally, the nitriding process also improves corrosion resistance due to the use of exotic fuels.

Engine Pro also offers a 4000 series valve that is designed for diesel applications. These are similar to the Nitro Black series, but the exhaust valves feature a bi-metal construction with Inconel for better heat resistance.
