The thing about chrome plating the intake is that the plating process often leaves a residue on the inside of the manifold. You may not be able to get to all the areas in the intake runners. The last thing I would want is a piece of chrome, copper, or nickel finding its way into the combustion chamber or valve train. It is aluminum and you can have it polished and/or clear coated though. The only other dilemma is to make the valve covers match. Vipermed makes those plate covers. But then the closest you can get to chrome or polished is to powdercoat with that silver jet hot coating. You cant polish or plate them since the valve covers are magnesium. Is that shiny enough for you?
