    These sand cast aluminum valve covers feature raised CHEVROLET script lettering and 7 fins. They have perimeter mounting with staggered or offset bolt holes for 1955 to early 1959 cylinder heads. The mid height design clears many roller rockers.

    Benefits:

    • Traditional CHEVROLET script and fins
    • Heavy duty sand cast aluminum construction
    • Thick flange will not tweak when bolts are tightened
    • Staggered/offset bolt pattern for 1955 to 1959 cylinder heads
    • GM licensed

    These valve covers do not have a provision for PCV, breather or oil fill because the original valve covers did not have a provision for PCV, breather or oil fill. This was done in the intake manifold.

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

    These valve covers fit Chevy small block GM cylinder heads with the staggered or offset bolt pattern. Four bolts on the perimeter of the flange hold the cover on the head. This bolt pattern was used from about 1955 to 1959.

    These valve covers are larger than stock. Check for clearance for larger covers before ordering.

    1950 Chevy Panel Van

    Patrick installed these PML valve covers on his 1950 Chevy Panel Van. The engine is a 1958 Chevy 283 V8. He purchased the polish finish valve covers and customized them with paint across the center to match his van and updated engine compartment.

    1956 Chevy 265 V8

    Chuck installed these PML valve covers on his 1956 Chevy. The 265 engine is original with 62,000 miles.

    Initially, the covers would not installed because the valve springs were hitting the inside of the covers. The valve spings closest to the bottom two holes rubbed on the indentations for the bolt holes. Grinding off some material made enough clearance. He also needed to grind a small notch next to the intake manifold. This may be specific to the 265 engines, which might have a different fit than the 283 engines that came out in 1957.

    PML valve covers are sand cast aluminum, so they have thicker walls, are taller, and have a rougher texture.

    Many original valve covers were die castings or stamped steel. Both have a smooth surface.

    The images below show this PML valve cover compared to a typical die casting, GM part 3726086.
