How can I make my slant six exhaust manifold look great?

Cruiser- did you paint that Valve Cover. It looks like the right color. Brake Booster looks good too
I did not paint the valve cover. The guy who installed my cylinder head did. It doesn't look very good, to be honest. No worries though, as I'll be pulling and painting the engine next month. The brake booster was professionally rebuilt, which included gold anodizing the vacuum booster housing. Looks exactly like the way they came from the factory. Sadly, the gold anodizing on these boosters wore off pretty quickly and after about three years they all looked terrible. The decal is factory correct. The number on this decal is the last two digits of the booster part number. This decal is available as a repro.
