I'd say skip the header. I have a Thorley tri-y header, and it's ok, but not worth the $ nor the hastle of install (5 of my exhaust manifold studs ended up stripping out of the head).

Stay with the factory manifold and upgrade the tailpipe, cat, and muffler.
Then use the rest of the money you saved put it towards a new cam, differential locker, or sliders in a few more months.
