These valve covers are polished sand cast aluminum.
The polish finish is not like chrome. Since these valve covers are sand castings which have been hand polished there are always some slight imperfections.Read here about Finishes and Construction of PML parts.
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.
