    • Script and fins are part of the casting and raised above the surface
    • Heavy duty sand cast aluminum construction for thick walls
    • Open interior to work with many roller rockers and stud girdles
    • Option for PCV, breather and oil fill holes
    • Gasket flange will not bend or flex when bolts are tightened for a leak–free seal
    • Mounting hardware provide with the covers
    • Made in USA

    This script was common on engines with the 331, 365, 390 and 429 engines found in 1949 to 1967 models. For PML valve covers for those engines see PML Part Number 11073.

    PML added these valve covers to our product line for 368, 425, 472 and 500 Cadillac engines because of many customer requests.

    We have one set of these on special: SPECIAL 376.

    Finishes

    These valve covers are sand castings. So they have the texture of sand. This texture usually is visible through the powder coat or paint, similar to an orange peel look and feel.

    When the valve covers are powder coated, the top of the fins and script are brushed so the design stands out.

    When polished, the area between the fins and script is not polished to provide contrast and highlight the design.

    Read here for more information about finishes and construction of PML parts.

    Gaskets

    Uses stock gaskets (not included). We recommend cork or cork composite gaskets.

    PML sells cork composite gaskets for these valve covers which can be ordered over the phone.

    Inside of Valve Covers

    Click on image to view larger in a new tab or window.

    These valve covers have an open interior so that there is clearance for many roller rocker systems.

    The donut shapes on the inside add thickness so this area can be machined for PCV, oil fill caps or breathers.

    PCV, Breather and Oil Fill Holes

    PCV, breather, and oil fill holes are optional. Details:

    • PML machines holes to order
    • This is custom machining and carries an additional fee, custom machined orders are not returnable
    • Holes can be machined on the top in the finned area or in the middle of the intake manifold side
    • Holes machined on top over covers remove some fin area but do NOT interfer with the CADILLAC script
    • On the inside, the circular bosses, which look like rings or donuts, indicate locations where holes can be machined on the top
    • Only holes on top can be threaded for an oil cap
    • A billet oil cap is available
    • Machining must be ordered over the phone

    If there is a PCV or breather hole, a separate oil fill hole is not needed. Oil can be added by temporarily removing the breather or PCV valve.
