    PML designed these small block Chevy valve covers with fins and CHEVROLET script for a classic look to dress up the engine compartment.

    Benefits:

    • Classic CHEVROLET script and fins
    • Heavy duty sand cast aluminum construction
    • Thick flange will not flex when bolts are tightened
    • Mid height design to work with many roller rocker systems
    • Standard perimeter 4 bolt mounting to cylinder head found on 1959 to 1986 Chevy small block engines
    • Mounting bolts provided
    • Made in USA

    The script is cast into the cover and raised. On powder coated parts, the powder coat is shaved off the top of the script. On polished finish parts, the band is not polished to provide contrast to the script.

    Configurations vary! Before ordering go to our CHECKLIST.

    We have some of these valve covers on SPECIAL.

    General Motors Trademarks are used under license to PML, Inc.

    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.

    See SPECIFICATIONS for information to determine if these valve covers will for your engine configuration. Always check before ordering as PML has a restocking fee.

    Will These Valve Covers Fit On Your Engine?

    Engine configurations vary! Before ordering use our CHECKLIST.

    We have a Loaner Program if you need a cover to test fit.

    Optional PCV, Breather, and Oil Fill Holes

    PCV/breather/oil fill holes are optional. PML makes these valve covers without holes and can machine holes when needed for an engine configuration.

    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.

    Compared to Die Casting

    These images show this PML valve cover compared to a typical die casting, GM part 3726086. Many original valve covers were die castings or stamped steel. Both have a smooth surface.
