Description
The Billet Specialties Big Block Chevy Billet Aluminum Tall Valve Covers (Streamline Series) bring a modern, high-contrast aesthetic and valvetrain clearance to your Big Block V8 engine bay. Crafted from high-grade aluminum, these Streamline Series covers feature a durable Satin Black powder-coated finish accented by a precision CNC-machined, hand-polished center plate.
Standing at a tall 3-3/4" internal height, these valve covers are specifically engineered to provide ample clearance for high-performance valvetrains, including large-body aluminum roller rockers and stud girdles.
Key Features & Design Highlights
High-Contrast Streamline Aesthetics: Finished in a rich Satin Black powder coat paired with a polished CNC-machined aluminum center accent plate.
Internal Metal Baffles & Grommets: Features a 1-1/4" diameter breather hole equipped with internal metal baffles and rubber grommets to prevent oil splash and mist from escaping through the breathers.
High-Grade Aluminum Construction: Precision-machined for flat flange surfaces that resist warping under extreme cylinder head temperatures.
