Could use 03 Cobra cams and 99-01 Cobra cams. The 03 cams are designed for SC application (duh) so you wouldnt want to use them for a turbo or nitrous application. Even the Aviatior (sp) cams are an option. I remember talking to Sam about the samething a month or so ago but I cant remember what would be ideal for NA. Give him a call and see or try a search on corral. Good luck.
