These valve covers feature the classic 1949 style CADILLAC script. The script gives an old school feeling to the more modern, powerful Cadillac V8 engines. Nine fins complement the script to complete the design.

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

The script and fins are part of the casting and raised above the surface. When the valve covers are powder coated, the top of the fins and script would be brushed so the design stands out.
In a similar way, when polished, the area between the fins and script would not be polished to provide contrast and highlight the design.

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 the the 331, 365, 390, 429 Cadillac engines, please see PML Part Number 11073.

Inside of Valve Covers

Inside of PML Cadillac valve covers

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. These locations can be machined for PCV, oil fill caps or breathers.

PCV, Breather, Oil Fill Options

These covers do not come with holes but they can be machined on the top or the side. Holes do not interfer with script. PML can machine holes for a $45.00 machining charge per hole.

See pictures of similar PML Cadillac valve covers with holes drilled and oil caps in this PDF file. A separate window will open and the file will load (may take a minute).

A billet oil cap is also available.

Please call to order for machining or billet oil cap.

Dimensions: 3.6 inches tall. For more dimensions, click here for dimensions.

Finishes: These valve covers will be available in the natural as-cast finish, black powder coat finish with shaved fins and script, and polished finish. The as-cast and polished finishes are show in the images above. We do not yet have a picture of these valve covers in the black powder coat finish.
