    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 clean design works well in restorations and vehicles where script or fins is not desired.

    Benefits:

    • Plain top for customization or clean appearance
    • Heavy duty sand-cast aluminum construction
    • Thick walls for strength
    • Gasket flange will not bend or flex when bolts are tightened for a secure seal
    • Mounting hardware included

    Some customers engrave or put a their own custom design on the top. Because PML valve covers have thick walls, the top surface is suitable for this. PML does not offer customization. We recommend contacting Scott at Advanced Auto Graphics in Kansas, 620-562-3563.

    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.

    No pictures of installations available.

    Because these are sand castings, the as-cast finish parts will not be smooth as they will have a texture of sand. Read about finishes and construction of PML parts.
