Well, dont go stock looking, then there would be no point to it. Red would make it look like you were going for a wanna-be type R look (which isnt too bad as long as you arent trying to be a poser), and matching the stock paint could leave you with a shittly looking valve cover after about a year. (paint on valve covers sucks) I'd hit it with red or gunmetal or something. Be sure to use powder coat and not paint. Even engine paint looks like ass after a year of heat and oil.
P.S. Nevermind. finally read the rest of the thread. weee!
