Moroso has introduced GM LT1/LT4/L86 Billet Aluminum Valve Covers Part No. 68494 that are bolt-on replacement for Corvette/Camaro and other applications with LTI/LT4/L86 cylinder heads.

Each valve cover is CNC machined from a billet aluminum bar and is 1-½” tall to clear most engine accessories and aftermarket valve train assemblies. Both valve covers have ports to tie into the factory PCV lines and have integral coil pack mounts that accept OEM & LS2, LS3, LS7 & L98 style coils.

One valve cover features a oil fill with a CNC machined cap with o-ring and a mounting tab for the factory dipstick tube. Cylinder head mounting area has an o-ring groove that accepts GM#12619787 Valve Cover O-Ring Gasket. Even though these valve covers are light in weight, they are thick enough for the engine builder to be able to add fittings at the top and ends. The covers can be polished, chromed, powder coated or left as-is for a race look.
