Description
The Billet Specialties Center-Bolt Chevy Billet Aluminum Valve Covers (Ball Milled) bring clean, high-tech styling and an award-winning mirror shine to your Small Block Chevy engine bay. CNC-machined in the USA from high-grade aluminum, these tall-profile valve covers feature classic ball-milled accent grooves running down the top surface.
Engineered specifically for 1987 and newer Small Block Chevy center-bolt cylinder heads, these valve covers replace factory stamped steel or composite covers with a heavy-duty, rigid aluminum housing designed to resist warping and prevent oil leaks.
