Scotch brite pad saturated with Mothers Mag polish for the clamps at the head took the surface rust off. May not be so easy on the bike tho!
Do keep in mind the headers are plated. Sand paper and repeated scuffing will lead to short turn times before they rust again once through the plating (nickle plating???).
