Milodon's Street Stainless Valves are independently tested to flow better and produce more horsepower, right out of the box. These street valves feature one-piece quality forgings, premium 21-4N material on the exhaust and high-grade stainless on the intake. Smooth machined valve heads ensures high, effecient flow and hard chromed stems reduce wear for long lasting performance. A single keeper groove gives greater valve tip strength. In cases of regrinding, a large seat margin allows for many regrinds. These street stainless valves are perfect for the Sportsman racer or everyday rebuild. Available for popular GM, Ford, Chrysler applications.
