These valve covers feature a tall height and a clean design with raised fins. This PML design located the PCV/breather/oil fill hole in the center on the intake side. Two recessed bolts per cover (stock uses four) hold the cover on the engine. The sand cast aluminum construction provides stiffness so four bolts are not needed to apply pressure evenly to the gasket.
The valve covers fit the center bolt heads used on 3rd Gen Chevrolet small block engines. Production of these heads began in 1999. Versions of these heads are found on Corvette, Silverado/Sierra, Tahoe/Yukon, Camaro/Firebird, and GTO's. Early Gen III engines in 1997 and 1998 have 9 bolts on the perimeter of each cover. These valve covers work with the center bolt configuration.
Stock cover shown here. PML valve covers are taller than stock and clear Jesel roller rockers. The stock covers require four bolts and the oil fill is on the top. With PML covers, a hole on the intake manifold side is used for oil fill, in keeping with the clean, classic design.
PCV, Breather, and Oil Fill
These valve covers have holes cast into the intake manifold side of the cover for PCV, oil fill and breathers. The holes are 1 inch in diameter. Some applications require larger holes, for example 1 1/4 inches. The cast-in holes can be machined to the larger size if needed.
Images below show an example set-up with a a push-in breather (center image) installed and a PCV valve with grommet on the right. PML machined the holes to the larger 1 1/4 inch size. Push-in breather and grommet both available from PML.
This shows the inside of the cover machined for the push-in breather with the breather installed: 
Gaskets
PML supplies gaskets, of our design, with each set for a secure seal.
Coil Packs
Coil packs will need to be relocated in order to use these valve covers.
PML custom makes and sells P/N 11083 cable extensions to allow for coil pack relocation (available separately).
Relocation of the coil packs is up to the customer.
Baffles
Valve covers feature internal cast-in baffles. Inside of cover pictured at right. The baffle is in the center of the cover where the PCV/oil fill/breather hole is located. The hole is 1 inch but can be machined to 1 1/4 if needed.
