Moroso Chevrolet Big Block Valve Cover w/Billet Rail - 3in - Exhaust & Intake Pockets - Aluminum

What you get with this Moroso valve cover kit is a pair of well-built aluminum valve covers, each featuring a substantial 3-inch height. They also include a billet aluminum rail that runs along the top, and each cover is designed with specific pockets to accommodate exhaust and intake valve train components. These are designed for Chevrolet big block engines, offering a significant upgrade over stock components for those looking to optimize their engine's performance and appearance.

These valve covers are crafted from aluminum, which makes them lighter than steel alternatives and helps with heat dissipation around the valvetrain. The 3-inch height provides ample clearance for high-performance camshafts, roller rockers, and other valvetrain upgrades that might not fit under a standard-height cover. The integrated billet rail adds rigidity and a clean, finished look, often used for mounting PCV systems or other accessories. The exhaust and intake pockets are a thoughtful touch, ensuring there's enough room for larger valve springs or rocker arms without interference, which is crucial for preventing damage and ensuring consistent engine operation.

When installing these, you'll want to ensure your engine block is clean and that you have new valve cover gaskets. Because these are a performance part, it's always a good idea to refer to the manufacturer's installation instructions to confirm any specific torque sequences or recommendations for your particular big block application. This setup is ideal for anyone rebuilding or modifying a Chevrolet big block where clearance and a high-quality appearance are important.
