Tom,
I read the article definately worth the read. Unfortunately, there isn't much mention of the work hardeneing and fatigue I've heard about with headers. I heard from my machinist that the boat headers that are made os ss ork harden and when they crack are not amendable to welding. I wonder if this is true?
