Chevy™ Small Block, Perimeter Mount, Pre-1986, CHEVROLET® Script and Fins
Valve Covers

P/N 10430

These PML valve covers are standard perimeter mount covers for pre-1986 small block Chevy engines. The CHEVROLET script and fins are cast into the cover and are raised. On powder coated parts, the powder coat is shaved off the top of the script and the fins. These valve covers feature cast-in baffling and a mid-height design that will clear most roller and/or ratio rockers.

PCV, Breather, and Oil Fill:

PML makes these valve covers without holes. The covers have a recessed cast-in location on intake manifold side that can be machined for PCV, breather, or oil fill. PML can machine holes for $40 per hole, and holes and be either 1" or 1.22" in diameter. Please call to order if you would like PML to machine a hole for you.

At the end of 2010, we updated our design to remove the indented recessed location on the intake manifold side of the covers below the Ch. Some models of PML's valve covers have the recessed location and others do not. Either way, the covers can be machined.

We have one polished set on special.

Ken Bethel is putting this 1980´s engine in his 1955 Chevy. He said these PML small block Chevy valve covers "are exactly what I had envisioned when I began the search for just the right valve covers for my 55 Chevy project.".
