I would definatly go DMD, since they are so cheap now from the Ford Dealer, maybe a chip or even support our locals with a heatshield. Also be sure to run about half a quart more oil than recommended that way you don't have to get a new engine, and don't use a Fram filter. Maybe if I were you I'd go with springs, struts, and rims, since you've already gotten the GO taken care of now time for show.
