No headers fit a 273 Barracuda with Power Steering? Help please!

Ive just started playing around with the performance of my 66 Barracuda 273 and Im having a lot of trouble finding headers to fit. On the left side of the engine sits the power steering unit so there is literally no room for anything other than the stock set up. What do other people do to get headers or block huggers to fit? Any brands make them?

Thanks!
