Our Victor Series valve covers have a black powder coated finish that features a finely textured surface for a pleasing and unique appearance. This is the same finish youll find on our top-of-the-line Edelbrock/Musi 555 Crate Engine. These valve covers are manufactured from die-cast aluminum and machined with 1-1/4 breather hole. Overall height is measured from base to top at the highest point.
