You didn't mention mileage on the bike? When I changed out my cams, just installing SE adjustable pushrods made the top end quieter. Lifter noise can sound like it's coming from the rocker boxes too. New lifters, like the ones from AMS are not too expensive. Oh, and the spring is in the Cam plate - great picture on harleyhogs site...
