B&B Aluminum Covers are 5/16" taller than stock, and are engineered to clear alternators, air conditioning compressors, and power brake boosters. Unlike factory covers, the bolt towers are machined to clear roller rocker arms. Multiple part numbers cover the entire spectrum of small-block Chevrolet applications, including covers with baffled breathers, PCV holes, and screw-in oil filler caps. 1993 and newer vehicles equipped with 140 amp alternators require extra clearance to accommodate the larger alternator. B&B Performance will stock these covers and are available at minimal extra cost. Designate this option with letters "AN" after part number when ordering.

B&B valve covers are available with natural diecast finish or polished to a brilliant shine. The covers' smooth, flat tops are ideal for personalized engraving and custom graphics. These new center hold down aluminum valve covers have the same performance features as B&B's famous competition versions. Aircraft-quality precision casting combines strength with lightweight. Extra-thick flanges, reinforced bolt bosses, and gasket retainers prevent messy oil leaks.
