Moroso has introduced part No. 68476, billet aluminum GM LS valve covers with Holley/Smart Coil Pack Mounts. They fit GM LS series OEM and aftermarket cylinder heads. Each valve cover is CNC machined from a billet aluminum bar and their cylinder head mounting area has an O-ring groove that accepts Moroso Part No. 93025 or GM Part #12612045 O-ring.
The integral coil pack mounts accept Holley and other “Smart” style coils and are 2-1/2″ tall to clear most aftermarket valvetrains. Each cover features a port that a Moroso Part No. 68857 breather or COPO breather snaps into, and can then be unsnapped to use an oil fill.

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.
