PML sand cast aluminum construction adds thick walls and gasket flanges so there is not any distortion when bolts are tightened.

    The classic CADILLAC script and small fins are cast into the cover and raised. The script replicates the 1949 GM CADILLAC logo. These PML valve covers are licensed GM products.

    On powder coated parts, the powder coat is shaved off the top of the script and fins. On polished finish parts, the area between the fins and the script is not polished so the script and fins stand out.

    These PML valve covers are standard flange mount covers for V8 small block Chevy engines (265, 283, 327, 350, 400). The valve covers mount on to the cylinder heads with four bolts on the perimeter, directly across from each other. These valve covers can fit the small block engines originally produced in 1959 to 1986 and many new crate motors.

    We fit each cover on a stock GM cylinder head with stock rocker arms.

    Our approach to PCV and breather holes is unique so we made a PDF file with pictures and details: PML Specifications on Oil Fill, Breather and PCV (click to view) (a new window or tab will open with a PDF file).

    If these PML valve covers are ordered with PCV, oil fill and breather holes, PML will machine one hole in each cover on the intake manifold side and include a PCV grommet, a push-in breather, and an oil fill tube.

    Call if your engine configuration requires one hole or to discuss your requirements.

    PML machines the valve covers to order in our shop. We use four or five different tools, shown in picture, on a CNC machine to create neat, leak-free holes. Spot facing provides a smooth sealing surface for grommets.
