This set of valve covers is on special because of an excessive amount of porosity all over the covers. See pictures for examples.
This gasket is available and recommended: Gaskets for Small Block Chevy Engine Valve Covers
New mounting bolts are included.
Holes can be machined for PCV, breather and oil fill. This is custom machining and there is an extra charge and it must be ordered over the phone. Link for PDF on PCV and breather holes.
Be sure to read this CHECKLIST before ordering.
For reference, see our regular Chevy Small Block, 1959 to 1986, CORVETTE Script and Fins, PML Part Number 11026.
This special should fit and function like a regular part.
