Chevy™ Small Block
GM LT1/LT4, Center Bolt
CORVETTE® Script and Fins
Valve Covers

P/N 11041

These valve covers feature vintage CORVETTE script lettering and fins and strong cast aluminum construction. The script and lettering are raised. PML made these classic style valve covers for center bolt small block engines, GM Generation II LT1 and LT4.

PML designed these covers so that the top surface where the fins and lettering are is completely clean.

The design removed two bolts and the PCV/breather/oil fill holes from the top surface and added the script and fins. The sand cast aluminum construction is so much stiffer than stock that you do not need four bolts to apply pressure evenly to the gasket.

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. Click here.

Many crate engines, 1987-1998 Silverado, Sierra, Suburban, Tahoe, Corvette, Impala SS, Camaro Z28, and mid-90s Pontiac Camaro and Firebird have small block center bolt heads.

Valve covers feature internal cast-in baffles. Click here for picture of inside. A image will open in a separate window.

PCV, oil fill, or breather holes may be machined on the intake manifold side, in the front or in the rear.

Optional PCV, Breather, and Oil Fill Holes

Covers do not come with holes machined for PCV, oil fill or breathers. Two locations on the intake manifold side can optionally be machined. Baffles are cast into the interior of the cover in two locations opposite where the holes would go. Please call to order if you would like PML to machined these holes. There is a machining charge. For more information, see this pdf file on machining, grommets and breathers.

This 1932 Ford at the Grand Nationals in January of 2011 shows these PML valve covers in polish finish with black paint between the fins and script. The engine is a ZZ3 350 and the transmission is a 700R4. This roadster belongs to Bryan in Riverside, CA and kindly allowed us to take some pictures.
