These valve covers are available in the natural as–cast finish.

Read here about finishes and construction of PML parts.

The as–cast finish can be custom painted or powder coated by a local shop if desired. Note that these are sand castings and have the texture of sand. This texture usually is visible through the powder coat or paint, similar to an orange peel look and feel.


Uses stock gaskets (not included). We recommend cork or cork composite gaskets.

PML sells cork composite gaskets for these valve covers which can be ordered over the phone.

PCV, Breather and Oil Fill Holes

PCV, breather, and oil fill holes are optional. A billet oil cap is also available. Holes can be machined on the top or the side. On the interior, the top of the valve cover has bosses in typical hole locations. PML can machine holes for a $45.00 machining charge per hole. Please call to order for machining or billet oil cap.
