These PML valve covers feature a classic appearance with raised fins and strong cast aluminum construction. PML made these fin-only style valve covers for center bolt small block engines, GM Generation II LT1 and LT4.
Award winning two-bolt design: Stock valve covers have four bolts holding the cover on to the engine. PML's two-bolt design removes the two center bolts for an attractive presentation. Because PML valve covers have thick wall sand cast aluminum construction, they are much stiffer than stock and need only two bolts to apply pressure evenly to the gasket. PML valve covers will not tweak, bend, twist or deform. No leaks and a great look to dress up your engine.
If PCV, oil fill, or breather holes are needed, they can be machined on the intake manifold side in the front or back (scroll down for more info).
These covers are slightly taller than stock to allow roller rockers. Please check for interference from a taller valve cover as some engines have a bracket or other parts that sit close to the stock covers
To install the covers using these gaskets, hold the gasket in place with your fingers and put your thumbs over the screws on the top. Then carefully fit the valve covers on the head making sure to get the groove on the covers lined up with the groove on the head. Put the exhaust side in first. Not getting the grooves lined up is a cause of leaks.
PML designed small block Chevy valve covers to work with many roller rocker systems, such as Jesel. However, our valve covers are not compatible with T&D Shaft Mounted Rocker Arms.
