No experience with the headers, but the engine looks great, Jared! Not many people have the guts to paint aluminum heads, but it sure keeps the 'stocker' look. I'm on the fence about painting them. Just make sure all the edges are smoothed and rounded off on that dipstick. You sure don't want to be shaving bits of metal off into your oil pan....unless you've fabbed up a wire dipstick, like newer cars have.
