These PML Nailhead BUICK V8 valve covers are designed for 1953 to 1966 Buick 264, 322, 364, 401 and 425 engines. PML valve covers are heavy duty and feature classic styling. The fins and script are cast-in (not engraved) and are rise over a quarter of an inch above the surface. Much thicker and stiffer than stock, these valve covers will not bend or flex and will make a secure, leak-free seal.

On the powder coat finish, the powder coat is shaved off the top of the fins and script.
These valve covers mount with two bolts per cover, included.
PML Buick Nailhead V8 valve covers come in two other designs, smooth side and full fin. PML also offers valley plates, spark plug wire covers and oil pans for the Nailhead V8.
For gaskets, PML designed these Nailhead Buick valve covers to work with stock gaskets.
Optional PCV, Breather, Oil Fill Holes
These covers can work with many applications. Some applications use the valley plate for PCV, oil fill and breathers. Some applications use the valve covers. Holes to accommodate PCV, oil fill and breathers can be machined if needed in three possible locations on these PML valve covers. The interior has reinforced rings for custom machining when needed. An oil cap is also available.
Images below show the interior of these valve covers with the reinforced rings for machining, valve cover machined with an oil cap on it, and machined hole with oil cap sitting next to the cover. If you click on a small image, a larger image will load in a separate window or tab.
PML has a machine shop on-site and can machine holes for $40 per hole. Please select machining option below and let us know the specifications for your hole(s).
Optional Machining for Roller Rocker Arms
Some engine builds use large roller rocker arms. Customers have reported that sometimes there can be contact with the front side wall of the valve cover. Because PML covers are heavy duty, we can machine a groove to add clearance. This is approximately a one inch wide groove about one inch down from the gasket surface.
PML has a machine shop on-site and can machine this groove for $40 per groove. Please select groove option below.
