BBC Cast Alm Valve Cover Set Tall w/Hole Polished

The Mr. Gasket BBC Cast Aluminum Valve Cover Set Tall with Hole Polished (Part No. 6858G) is a matched pair of tall-profile valve covers engineered for big-block Chevy engines. These polished aluminum covers feature breather holes and come complete with all necessary mounting hardware, offering a clean, finished look while maintaining proper crankcase ventilation.

Cast aluminum construction provides durability while keeping weight minimal—each pair weighs 9.07 lbs total. The tall profile accommodates high-rise intake manifolds and custom engine builds where standard covers would create interference. Pre-drilled breather holes allow proper air circulation without requiring additional modifications, and the polished finish delivers a professional appearance suitable for show vehicles, hot rods, and street engines alike. Hardware inclusion eliminates the need for sourcing fasteners separately.

This big-block Chevy valve cover set serves builders and enthusiasts who need reliable crankcase sealing with clearance for higher-rise intake configurations. The polished finish integrates seamlessly into engine bays where visual presentation matters—whether for competition, restorations, or street applications where an uncluttered, factory-plus appearance enhances overall aesthetic. Mr. Gasket's proven track record in performance engine sealing components makes these covers a dependable choice for serious builds.
