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 sand cast aluminum and feature classic styling with the traditional BUICK logo.

Benefits:

Vintage BUICK script
Fins and script are cast in (not engraved) and over a quarter of an inch tall
Thick wall construction so covers are stiffer than stock
No bend or flex for a secure seal
Taller than stock for some roller rocker systems

Made in USA

These valve covers mount with two bolts per cover, included.

On the powder coat finish, the powder coat is shaved off the top of the fins and script. On the polish finish, PML does not polish between the fins and script.

PML also manufactures Nailhead V8 valve covers with a smooth side, valley plates, spark plug wire covers, and an oil pan.

We have two of these on SPECIAL: Special #418 and Special #419

Specifications

Gaskets

Gaskets are not included with these valve covers. PML designed these Nailhead Buick valve covers to work with both stock gaskets and cork composite 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.

These valve covers can be machined with holes to accommodate PCV, oil fill and breathers if needed. There are three possible locations. The interior has reinforced rings for machining.

This is custom machining. PML has a machined shop on site and can machines these valve covers to order. Please call to discuss configuration needed and pricing.

An oil cap is also available.

Read this PDF file on PML Nailhead Valve Covers Machining Options for pictures and more information.

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.
