Got a set of 03 heads but Im staying N/A. I was looking at the FR500 cam kit ( http://home.flash.net/~ivc1/cobra/frcamkit.html ) after they were suggested to me by a friend. The kit is about $1400, is there any place that has is cheaper? Trying to shop around before I buy them. Anyone have any first hand experiance with these cams on a N/A setup?
