These Valve Covers are on special because one cover has porosity.
Additionally, the other cover has a little discoloration.
For reference, see our regular Chevy Small Block, Perimeter Mount, CHEVROLET® Script and Fins Valve Covers, PML Part Number 10430.
For a gasket, PML recommends one make of cork or cork composite, such as this one: PML Small Block Chevy valve cover gasket
These valve covers can be machined for PCV, breather and oil fill holes. There is a machining charge. Holes must be ordered over the phone for specials. See this PDF for details before calling or emailing.
This special should fit and function like a regular part.
This is sold as-is and cannot be returned. Please call to order.
