Buying Guide: Key Considerations for Mickey Thompson Valve Covers
- Fitment: Confirm engine model, year range, and head clearance to avoid contact with rockers or the hood.
- Material: Billet aluminum offers lighter weight and heat resistance; steel provides budget-friendly durability; chrome plating adds classic styling.

- Height and clearance: Tall valve covers may require additional clearance; verify intake, air cleaner, and hood compatibility.
- Hardware and seals: Look for hardware-included sets and gasket compatibility to ensure a leak-free seal.
- Aesthetics and finish: Choose between polished, black, or chrome finishes based on engine bay styling and other components.
FAQ
- What is a tall valve cover best for on a BBC? It provides more clearance for valve train components and can help with clearance over tall intake setups, while offering a bold look.
- Do all valve covers require breather holes? Not always. Some designs include breather holes, while others are hole-free and rely on separate ventilation solutions.
- Are billet aluminum covers more heat resistant than stamped steel? Generally yes, billet aluminum dissipates heat effectively and is lighter, though both types are durable for typical BBC use.
- Can I reuse existing grommets or gaskets with new covers? It depends on the cover design and gasket type; always use the recommended grommets and gaskets for a proper seal.
- Is chrome a good choice for daily-driven BBC engines? Chrome is visually appealing and classic, but may show heat and oil stains more readily than darker finishes; choose based on maintenance preference.
- How do I verify hood clearance with tall valve covers? Measure the total height of the cover plus any breather hardware and compare to the clearance between the engine and hood in your mount setup.
