CADILLAC?? 331, 365, 390, 429 Valve Covers


There is 2.48" from the gasket surface to the top inside surface.

These PML Cadillac valve covers are designed for 1949 to 1967 Cadillacs with 331, 365, 390, and 429 V8 engines with four bolt valve covers.

PML valve covers are heavy duty and feature classic styling. The fins and script are cast-in (not engraved). Much thicker and stiffer than stock, these valve covers have a machined gasket surface for a secure seal.

On the powder coat finish, the powder coat is shaved off the top of the fins and script.

These valve covers are perimeter mount, with four bolts per cover, included. Some early engines require center bolt mounting and PML does not have vavle covers for these engines.

PML Cadillac valve covers have an open interior and pockets to clear most roller rockers.

Most applications breath through the valley plate so these valve covers do not incorporate a provision for breathers or PCV.


We recommend using the 1949 to 1955 4-bolt gaskets. For example, our customers have reported that FelPro part number 5392 gaskets work well with these valve covers. PML designed these Cadillac valve covers to work with stock gaskets, available at many auto parts retailers.

Note that there are five different gaskets available. Later year gaskets (after 1955) may not work with these covers. Gaskets are not included with the covers.

PML Valve Cover Features:

Strong sand-cast aluminum construction
Thick side walls and gasket flanges that will not bend when bolts are tightened
Mounting hardware included
