These PML valve covers are standard flange mount covers for V8 small block Chevy engines (265, 283, 327, 350, 400). The valve covers mount on to the cylinder heads with four bolts on the perimeter, directly across from each other. These valve covers can fit the small block engines originally produced in 1959 to 1986 and many new crate motors.
We fit each cover on a stock GM cylinder head with stock rocker arms.
See SPECIFICATIONS for information to determine if these valve covers will for your engine configuration. Always check before ordering as PML has a restocking fee.
Loaner Program
We want to make sure you get valve covers that will work on your engine and you love looking at. With that in mind we have a program for borrowing a PML valve cover to test fit on an engine. Learn more about the PML Loaner Program.

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.

383 Stroker Hot Rod Carbs Clear Coat
Hot Rod Carbs built this 383 stroker for a Model A. The natural as cast finish valve covers were clear coated and they were happy with the result and hopeful the clear coat would not yellow. PML does not recommend or have any information about clear coating.

Will These Valve Covers Fit On Your Engine?
Engine configurations vary! Before ordering use our CHECKLIST.
We have a Loaner Program if you need a cover to test fit.
Gaskets
Gaskets are not included with these valve covers. PML designed these Chevy Small Block Perimeter Mount Valve Covers to work with cork composite gaskets.
Optional PCV, Breather, and Oil Fill Holes
PCV/breather/oil fill holes are optional. PML makes these valve covers without holes and can machine holes when needed for an engine configuration.

Our approach to PCV and breather holes is unique so we made a PDF file with pictures and details: PML Specifications on Oil Fill, Breather and PCV (click to view) (a new window or tab will open with a PDF file).
If these PML valve covers are ordered with PCV, oil fill and breather holes, PML will machine one hole in each cover on the intake manifold side and include a PCV grommet, a push-in breather, and an oil fill tube.
Call if your engine configuration requires one hole or to discuss your requirements.
PML machines the valve covers to order in our shop. We use four or five different tools, shown in picture, on a CNC machine to create neat, leak-free holes. Spot facing provides a smooth sealing surface for grommets.

Compared to Die Casting
These images show this PML valve cover compared to a typical die casting, GM part 3726086. Many original valve covers were die castings or stamped steel. Both have a smooth surface.
PML valve covers are sand cast aluminum, so they have thicker walls and have a rougher texture. The polish finish smooths the sand-like texture but the result does not look like a die cast or stamped steel cover.
