Finishes:

These heavy duty valve covers from PML for big block Chevy engines feature raised CORVETTE script and fins and top quality construction. The classic CORVETTE script is licensed from General Motors. These covers are the same for both the driver and passenger side for a consistent look. Some engines require a relief or indent in the driver side cover for the brake booster.

PML valve covers are sand cast aluminum. This is different than the original valve covers.

PML designed these valve covers using original GM cast iron heads. Chevrolet Big block engines include: 396, 427, 454, and the 502.

Engine configurations vary and PML cannot guarantee fitment. Check your engine configuration carefully before ordering.

• These valve covers are standard height on the inside but taller than stock on the outside because of the thick walls and script and fins on top.
• For engines without a brake booster

On the inside, some rocker arm systems have contacted an inside corner of the PML valve covers. Some customers have had to remove a bit material from the rockers.

Included with Valve Covers

These PML valve covers ship with new mounting bolts and PCV and breather grommets installed.

Inside of Valve Covers

These PML valve covers have oil drippers on the inside and the PCV and breather holes are baffled.

Gaskets

Gaskets are not included with these valve covers. PML designed these Chevy Big Block valve covers to work with cork composite gaskets.

Breather and PCV Holes

PML Chevy big block valve covers have PCV and oil fill/breather holes and baffles cast into the covers. The internal baffles help prevent oil blow-by out the PCV and breather holes. Either of these holes can also be used for oil fill by removing the PCV valve or breather.

These holes work with standard 1 1/4 inch grommets. The breather grommet has a 1 inch inner diameter for a standard breather cap. The PCV grommet has a 3/4 inch inner diameter for a standard PCV valve.

Checking Clearance

Engine configurations vary so please check for clearance for larger valve covers. The walls and gasket flange are thicker than stock and the fins and script add height to the top.

Look for clearance on the inside also, especially if you have roller rockers. A simple check can be made if you have the stock valve cover. Set the stock cover on the head and measure the distance, if any, between the gasket flange surface and the head. The PML tall version of these valve covers is approximately 3/8 inch taller.
