Finishes: Read about finishes and construction of PML parts.

These heavy duty valve covers from PML for big block Chevy engines feature raised CHEVROLET script and fins and top quality construction. The classic CHEVROLET 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.

For our tall height big block Chevy valve covers, see PML Part Number 9739.

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.
