PML designed these valve covers with the traditional styling of rounded corners and the classic CHEVROLET script. The script is cast into the cover and raised. On powder coated parts, the powder coat is shaved off the top of the script. PML valve covers are sand cast aluminum and strong. They will not flex when bolts are tightened.
These covers feature a mid-height design that will clear most roller and/or ratio rockers. There is no correlation between roller rocker ratio and fitment of our valve covers. It is based on the actual physical dimensions of the parts. These valve covers were designed using a stock head and the Jesel Roller rocker system. Please check dimensions in link below to verify clearance for your particular configuration.
These PML valve covers are standard perimeter mount covers for 1960 to 1986 small block Chevy engines (265, 283, 327, 350, 400).
This is a stock cover from a Chevrolet small block 283 engine. The stock cover is thin stamped steel and is (or was) orange.
Optional PCV, Breather, and Oil Fill Holes
PML small block valve covers are made without holes for PCV, oil fill or breather. The two most common engine configurations are (1) no holes required or (2) two holes required, one hole for PCV and one hole for a breather. (Note that either of those holes can also be used for oil fill.)

For engines that require PCV and breather holes on the valve cover, PML designed the casting to be thicker on the intake manifold side below the C where an internal baffle is located. This area can machined with a hole. This way, the top of the valve cover is left alone for a clean, classy appearance.
Image shows valve covers with holes machined, PCV grommet, push-in breather, and mounting bolts.
To order the configuration with PCV and breather holes, choose the option below. The option for PCV and breather holes includes one hole in each cover, a PCV grommet, a push-in breather, and an oil fill tube.

PML Small Block Valve Covers with T&D Rocker Arms
PML designed small block Chevy valve covers to work with many roller rocker systems, such as Jesel. However, our valve covers are not compatible with T&D Shaft Mounted Rocker Arms.
The T&D Machine Products Competition Rocker Arms are shown in the image at left. The shaft mounts are very tall, almost to the top of the rocker arms. The PML cast-in internal baffles will contact these mounts.
