Goof Off. That worked for me many times. Or you can use #0000 steel wool and some metal polish. That and a lot of elbow grease got the burnt remains of a skull cap off the pipe where it exits the head. Whether that's a header or not, it's probably exactly the place you're talking about. Very hot. Melted instantly... then had to ride home before working to remove it. Really baked on.
