These are heavy duty valve covers for Cadillac 368, 425, 472 & 500 engines with classic CADILLAC script raised above the top.
Benefits:
- Traditional CADILLAC script
- Open interior to clear many roller rockers and stud girdles
- Strong, sand cast aluminum construction
- No warping or tweaking due to thick walls and flange
- Machined gasket surface providing for a good seal to the cylinder head

The script is cast into the covers. On the powder coat finishes, the powder coating is brushed off the top of the lettering so the script stands out.
Claim to fame! These PML Cadillac valve covers were shown on Fast N' Loud "Big Red Caddy" episode, 1967 Convertible, Part 2, about 20 minutes in.
Finishes
These valve covers are not available in a polished finish. Please see our Machined Cadillac Script Valve Covers for a polish finish.
These valve covers are sand castings. So they have the texture of sand. This texture usually is visible through the powder coat or paint, similar to an orange peel look and feel.
