Moroso has introduced GM LT1/LT4/L86 Billet Aluminum Valve Covers Part No. 68495 to fit 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 valvetrain assemblies. One valve cover features an 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.
