Earle Williams makes headers that "go around" a stock steering box.

This is what they look like, but I'm using a C4 steering rack.

Like I said, if you are changing the firewall out for a custom one, I'd leave the engine in the stock position. I put my 502 1.5" forward but I still changed out the firewall to fit better with the engine. I personally think it looks a lot better smooth.
