I'm thinking the header wrap is the problem. Replacing the head pipe with no wrap and see what happens. The wrap kept the break from being obvious. I'm taking the wrap off the other pipe as well. Don't think it helped much with the heat anyway. Thanks for the input, never really thought about the wrap effecting the metallurgy of the pipe but after reading the posts and talking with an engineer riding buddy who builds large boilers I think that was my problem. Let you all know in a few thousand miles if it worked.
