Finishes
These valve covers are available in the natural as–cast finish.
The as–cast finish can be custom painted or powder coated by a local shop if desired.
These valve covers are sand castings. So they have the texture of sand. This texture usually is visible through the powder coat or paint, similar to an orange peel look and feel.

Gaskets
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.
PML designed these valve covers with locations that can be machined as needed. Holes can be machined on the top at the ends or on the intake manifold side.
PML can machine holes to order. This carries an additional fee and is custom machining. Machining must be ordered over the phone.
