Screwup after screwup... what to do?

I just bought a pair of the uncoated shorty Hedmans, I really like the way they fit in the pictures of jerry6's car in the link. I would already be ahead because these manifolds need the downpipes fab'd anyway and I'd save the price of getting them made a second time. I'll just bolt these on and use flex tubing so I can at least start the new engine and make sure it runs well before the headers arrive in a week. Thanks again guys if it wasn't for this site I would be dead in the water...
