PML Celebrates 25 Years with Commemorative Set of Custom Valve Covers

For 25 years now you’ve known PML as your best stop for sand cast aluminum differential covers, transmission pans, and valve covers. To celebrate our 25 years in business we are giving back, by giving to others.

PML has designed a set of custom valve covers to commemorate this milestone. These covers are now available for purchase. The covers are designed to fit small block Chevrolet engines with standard perimeter mount heads. They are polished with classic Chevrolet script machined engraved.

Over the years, we have taken pride in our ability to improve the look and operation of your vehicle. With the sale of these commemorative covers, we would like to do our part to help improve the lives of those less fortunate.

As a result, with each sale, a percentage of the proceeds will be donated to Boys Town and to Disabled Veterans Charities. Thank you in advance for your support.

Enjoy the covers.

PML Small Block Chevy valve covers can work with Edelbrock Performer RPM kits. However, the baffle on the PML valve covers will hit the pins unless the baffle is reduced in size. PML can machine the baffle to reduce the size if needed. For the Performer RPM, the distance between the pins is 1.16 inches. Out of the box our baffle is 1.2 inches. Call or email us if you need information.
