This set of valve covers is on special because of cosmetic blemishes.
One cover has an exercise amount of porosity on the script and the polished part of the top. The porosity is very tiny pinprick holes. There is also a small blob of aluminum between the "e" and the "v".
The other cover has a casting imperfection. There is a dip or lack of material on the top between the "C" and the "h".
These covers can be machined for PCV and breather holes but this must be ordered over the phone and there is a machining charge. See this PDF for details.
Review the CHECKLIST before ordering.
For a gasket, PML recommends one make of cork or cork composite, such as this one: PML Small Block Chevy valve cover gasket
For reference, see our regular Chevy Small Block, 1959 to 1986, CHEVROLET Script, PML Part Number 11106.
This special should fit and function like a regular part.
This is sold as-is and cannot be returned.
