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

P/N 8357-1

These PML valve covers are standard perimeter mount covers for pre-1986 small block Chevy engines. The CHEVROLET script is cast into the cover and is raised. On powder coated parts, the powder coat is shaved off the top of the script.

These covers feature 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.
