Ron, thanks for the PM, and that info does help me understand the process more. I stand corrected on the Mad Dogs, his tubes do have more weld than I remembered on the outside of the header flange. The front and rear tubes dont, but the center one are almost fully welded. Probably for the reasons you said. The hooker headers I have, are the ones that have no weld on the outside of the header flange, but they do have the "beads" on the gasket side that seal things up. I guess that is the difference.
Now go make me some headers!
