Finishes: Read about finishes and construction of PML parts.

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 valve covers have PCV and oil fill/breather holes and baffles cast into the covers. The internal baffles prevent oil blow-by out the PCV or breather holes. PML valve covers have walls and gasket flanges that are thick for strength and a secure seal to the cylinder head. The sand cast finish process provides an old-school look and feel.

PML designed these valve covers using original GM cast iron heads. Chevrolet Big block engines include: 396, 427, 454, and the 502. These covers use stock gaskets (not included).

PML also makes a tall height cover with out the brake booster indentation.

We have some of these valve covers that are on special. Click here for information on these specials.

Checking Clearance

Click for dimensions.

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. PML tall covers are approximately 3/8 inch taller than our standard height covers.

Brake Booster Relief

These valve covers feature a relief on the driver's side cover for the power brake booster. Our tall valve covers, PML Part Number 11042 do not have the relief.
