Cast in the USA of premium A356 aluminum alloy, heat treated and CNC machined to have an absolutely flat gasket surface. This retro design, when ordered in the polished finish, is fully polished between the fins, just like our valve cover. We like to keep polished surfaces as easy as possible to maintain. The unpolished finish is shot blasted. The mounting hardware is stainless steel button heads, because they are easier to clean around. This side cover has not been easy to find in recent years until now.
