    PML designed these valve covers for the classic hot rods of the 1950s and 1960s with the 348 or 409 Chevy™ W block engine. The CHEVROLET script and fins are cast into the cover and raised for a classic look.

    Benefits:

    • Classic styling with CHEVROLET script and fins
    • Heavy duty sand cast aluminum construction
    • Thick walls provide strength
    • Gasket flange will not bend or flex when bolts are tightened
    • Licensed GM product
    • Made in USA

    The script and fins are cast into the covers and are raised. On powder coat finishes, the powder coating is brushed off the top so the lettering and fins stand out. On the polish finish, we do not polish between the fins and script to add contrast.

    PML also makes 348, 409 valve covers without script or fins for engines needing a clean, unbranded design that can be customized.

    We have two set and one single on SPECIAL: Special 229 (single), Special 312 (set in polish finish), and Special 347 (set in polish finish)

    PML designed these valve covers for Chevy™ 348 or 409 W block engines. The clean design works well in restorations and vehicles where script or fins is not desired.


    PML fits each valve cover made on a 348 stock head during manufacturing. This verifies that the covers fit.

    PML valve covers have been installed on a many restorations and classics. Our thanks to those who have emailed us about their restorations and allowed us to share their pictures.
