Finishes: Read about finishes and construction of PML parts.

These PML valve covers are standard perimeter mount covers for 1959 to 1986 small block Chevy engines. PML designed these valve covers with the classic CORVETTE script for C1, C2, and C3 Corvette, including the Stingray.

The CORVETTE script and fins are cast into the cover and raised. On powder coated parts, the powder coat is shaved off the top of the script and fins. These valve covers are heavy duty with thick walls and gasket flange. The script and fins are part of the casting and raised.

The valve covers mount on to the cylinder heads with four bolts on the perimeter, directly across from each other. Vehicles with new GM crate engines use these valve covers to provide an old school, classic look and feel. We fit each cover on a stock GM cylinder head with stock rocker arms.

These covers fit on many engine configurations and feature a mid-height design that will clear many roller rocker systems. Configurations vary! See our Checklist. And use the dimensions verify clearance for your particular configuration.

Optional PCV, Breather, and Oil Fill Holes

Please read this PDF document on oil fill, breather and PCV set-up (click to view) for pictures and details.

PML small block valve covers are made without holes for PCV, oil fill or breather. The two most common engine configurations are (1) no holes required or (2) two holes required, one hole for PCV and one hole for a breather. Note that either of those holes can also be used for oil fill. We can also machine one hole in one cover (please call for this option).

PML Corvette Valve Cover, baffle shown

For engines that require PCV and breather holes on the valve cover, PML designed the casting to be thicker on the intake manifold side below the C where an internal baffle is located. This area can machined with a hole. This way, the top of the valve cover is left alone for a clean, classy appearance.

Image shows valve covers with holes machined, PCV grommet, push-in breather, and mounting bolts.

To order the configuration with PCV and breather holes, choose the option in the shopping cart. The option for PCV and breather holes includes one hole in each cover, a PCV grommet, a push-in breather, and an oil fill tube.

Please call to order if your engine configuration requires one hole or to discuss your requirements.

PML machining tools

PML machines the valve covers to order in our shop. We use four or five different tools on a CNC machine to create a neat, leak-free hole for PCV, breather or oil fill. Spot facing provides a smooth sealing surface for grommets.

To learn more, we have two videos. Please watch this step-by-step video of PML machining a PCV hole. We also have a step-by-step video of PML machining a hole for our push-in breather.

Roller Rockers

These PML valve covers work with many engine configurations and roller rocker systems. Configurations vary so please check your engine to determine if these PML valve covers will work for you.

Installations

Many makes and models have installed these PML valve covers, not just Corvettes. Our thanks to those who have sent us pictures of their restorations.

1930 Chevy Delivery Truck

1963 Corvette Fuellie

Matt installed these PML valve covers on his 1963 Corvette Fuellie. Matt knew that the PML valve covers would not fit without modification and was willing to try his hand at modifying them. He reported that the plenum side took a lot of modification. Although he did not want to cut into the top of the cover, he could not get the covers to fit otherwise. Our thanks to Matt for sharing his pictures.

PML does not promote or recommend or advise regarding modifications. This information provided for reference. Once modified no returns are possible.

Matt ordered the valve covers in the natural cast finish, machined with PCV and breather holes.

1967 Chevrolet Nova Sport Coupe With Brodix Heads

Gary installed these PML valve covers on his custom build with Brodix cylinder heads. On first attempt, the PML valve covers hit head and would not fit. By machining away about half of the lip on the bottom edge of the valve covers, Gary was able to get the covers to fit perfectly.

The first images shows the modification to the PML valve covers. The lip holds the gasket in place and is about 0.150 inches wide so there is plenty of material left even after machining. In the picture, the machined area is shiny.

Gary wanted the look of a L79 SBC pulled out of a Corvette. He was not trying to create a L79 Nova SS. He created the old time look of going to the Chevrolet dealer and buying the engine over the counter or pulling one from a wrecked Corvette from the wrecking yard. Engine is a SBC with a Comp Cams flat tappet cam, Brodix aluminum heads with a 700R4 overdrive transmission and a heavily modified Heidts front clip.

1967 Corvette Coupe

Dave installed these PML valve covers on his 1967 Corvette. He removed the original 327 engine and built a 427 small block using a Dart SHP block, Brodix IV heads with steel Comp Cams Extreme Duty roller rockers.

Dave ordered the valve covers in the natural cast finish, machined with PCV and breather holes and baffle clearance. The machining worked well and the valve covers fit the heads with the roller rockers.

1968 Iso Grifo

Ivan installed our natural cast finish CORVETTE valve covers on his 1968 Iso Grifo. The valve covers highlight the 383 Stroker Corvette engine. There was some interference between the springs and the internal baffle but with a Dremel tool and some patience everything worked fine.
