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.Installation Notes: • Polished with gloss black finish between the fins • Overall Height: 4.40” Tall Profile • Some tall profile valve covers will interfere with air-conditioning compressors, EGR valves and power brake boosters. • Will not fit 1986 & later Corvette aluminum heads or 1987 & later S/B Chevy cast iron heads.
