Valve Cover,Chevrolet Big Block,w/Raised Chevrolet Script-Tall

Chevrolet?? 396, 427, 454, & 502 Big Block With Raised CHEVROLET Script, Tall Valve Covers


These PML valve covers feature raised CHEVROLET script and fins. They are taller than stock and fit Chevy big block engines. The valve covers have PCV and oil fill/breather holes and baffles cast into the covers.


These covers are 3/8-inches taller than our standard height covers to fit over many roller rockers, such as Jesel. Read under installations below for possible modifications. 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).


For our stock height big block valve covers, P/N 9737.


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.
