I've ran, and I'm currently running Champion aluminum radiators. Cheap, Chinese from ebay usually 180 bucks to the door. Fit good, maybe just oval a hole or two. Never had them leak, and they cool well. As far as headers, there is a big price range. Ebay/Summit is full of cheapies, and then you can spend more towards Dougs/TTI's. Bare, painted black, or ceramic coated will also influence the price. I personally like Dougs for fitment.
