Award Winning! At the 2018 SEMA show, these valve covers won a 2019 Global Media Award.

Finishes

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.

When the valve covers are powder coated, the top of the fins and script are brushed so the design stands out.

When polished, the area between the fins and script is not polished to provide contrast and highlight the design.

Gaskets

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

Inside of Valve Covers

These valve covers have an open interior so that there is clearance for many roller rocker systems.

The donut shapes on the inside add thickness so this area can be machined for PCV, oil fill caps or breathers.

PCV, Breather and Oil Fill Holes

PCV, breather, and oil fill holes are optional. Details:

• PML machines holes to order
• This is custom machining and carries an additional fee, custom machined orders are not returnable
• Holes can be machined on the top in the finned area or in the middle of the intake manifold side
• Holes machined on top over covers remove some fin area but do NOT interfer with the CADILLAC script
• On the inside, the circular bosses, which look like rings or donuts, indicate locations where holes can be machined on the top
• Only holes on top can be threaded for an oil cap
• A billet oil cap is available
• Machining must be ordered over the phone

If there is a PCV or breather hole, a separate oil fill hole is not needed. Oil can be added by temporarily removing the breather or PCV valve.
