Fits GM LS SERIES stock and aftermarket cylinder heads
2-1/2" tall to clear most aftermarket valvetrains
Each valve cover is CNC machined from a billet aluminum bar
Cylinder head mounting area has an o-ring groove that accepts Moroso No. 93025 or GM Gasket
One cover features a oil fill with a CNC machined cap with o-ring
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
