The Edelbrock 4263 Elite II Valve Covers are designed for Chevy 262 - 400 V8 1959 - 86 applications. This new line of Elite II valve covers feature a design that is influenced by the original Elite Series originally released in 1985, but with a new modern take on this classic look. They're made from heavy - gauge, die - cast aluminum and are finished off with a show quality high luster polished finish. The raised fins are accented by a contrast gloss black finish between the fins for the definitive Elite Series look. Our tall profile valve covers are 2 taller than stock, and clear most roller rockers and valvetrain components. Our low profile valve covers clear all air - conditioning, alternator brackets and aluminum rockers. Overall height is measured from gasket flange to top at the highest point.
