Thanks much guys... I'm in a holding pattern right now.
I cut up the OLD driver's side header and just barely got enough straight tube from it to get the new header done.
I think I might be ok on the pass side. It had more straight tube due to not having to get around the steering column than the driver's side did.
I might luck out and just have to spend some time at the wire wheel removing old header paint.
But again, thanks for the efforts, and I will call those companies first if I wind up needing more tubing.
