shorty truck headers for tight fit with power steering

http://m.summitracing.com/parts/sum-g9045

I was wondering if anyone has tried these and knew how they fit a 360 LA engine with power steering? The issue I'm having is that the only thing that fits so far that I've got is a stock 318 manifold, but the flow will be severely hampered. I've got a 360 with ported j heads, 340 cam, edelbrock intake and tq up top. I used to have long tube headers but they were just too much of a pain.
