COLORS:
These PML big block Chevy valve covers feature sand-cast aluminum construction with baffles to prevent oil leaks and classic CORVETTE?? script and fins. The valve covers have PCV and oil fill/breather holes cast in.


These big block engine Corvette covers do not have a brake booster cut-out on the driver's side in response to customer requests. (If you need a brake booster cut-out, please see our stock height big block valve covers.)


They are 3/8-inch taller than our standard height covers to fit over many roller rockers, such as Jesel. If you have the stock valve cover, a simple check can be made to see how much clearance you need. Set the cover on the head and measure the distance between the gasket flange and the head. Our cover is approximately 3/8" to ???? taller then the stock cover.


The covers use stock grommets and gaskets (not included).


To get the PML covers to fit, he rounded off the left side corners on two of the roller rockers. The valve covers fit great after grinding a bit off the roller rockers on #1 intake and #6 intake (one intake rocker on each side of engine). He did not remove any material from the valve covers. He was told later by an engine machinist that this procedure is virtually always necessary when you try to put roller rockers on a big block chevy.


PML Valve Cover Features:

Strong sand-cast aluminum construction
Thick side walls and gasket flanges that will not bend when bolts are tightened
Cast-in internal baffles
Mounting hardware included
