Moroso's fabricated aluminum valve covers give Ford 429/460 big-block builders a clean foundation that performs as well as it looks. Constructed entirely from high-quality aluminum, these covers shed significant weight compared to stamped steel units while offering surface options that stamped steel cannot match. Available in two height options, 2.5-inch or 3.5-inch tall, to suit a range of head and rocker configurations.
Precision sealing starts at the rail. A one-piece billet rail is CNC machined to a precision-flat surface, eliminating the warping and uneven contact points common to fabricated covers without a machined rail. That flat mating surface lets the gasket seal fully and consistently, allowing the engine to pull greater vacuum for improved ring seal and a measurable gain in power retention.
Built for the custom shop and the engine builder. The broad, flat top surface is intentionally designed to accept engraving, making these covers a natural choice for builders who want to personalize a show engine or display a shop logo. The aluminum construction also accepts polishing, chrome plating, powder coating, or can be left in its raw fabricated finish, giving builders full control over the final appearance.
Product Benefits
- Fabricated Aluminum Construction: Lightweight and strong, with far less mass than equivalent stamped steel covers.
- CNC-Machined Billet Rail: Precision-flat sealing surface reduces the risk of oil leaks at the gasket interface. Improved Vacuum Seal: Airtight fit supports greater crankcase vacuum, contributing to better ring seal and power.
- Engravable Top Surface: Wide, flat panel gives engine builders a clean canvas for custom lettering or logos.
- Finish Flexibility: Compatible with polishing, chrome, powder coat, or left raw as fabricated.
- Two Height Options: Available in 2.5-inch or 3.5-inch tall to fit different rocker arm and valve train configurations.
- Direct Fitment: Sized for Ford 429 and 460 big-block applications.
Note: Fits Ford 429 and 460 engines. Select 2.5-inch or 3.5-inch height at time of order to match your specific valve train clearance requirements.
