HP Manifolds

This has been a very interesting thread. I am building an extremely low budget 67 Valiant with a 440. The exhaust is not purchased nor planned at this stage. The sheer cost of swap headers scares me frankly, and it destroys the 'budget' plans. So all the previous being said, does anyone sell the needed cast manifolds, with appropriate mods completed or not, and is the price difference worth the effort? I would love to find a way to get the fumes outa the motor to somewhere under the car for a couple hundred bucks or so.
