Thanks to all of you for the feedback... After doing more research, I ended up going with the Lemons headers -- 2 1/8" primaries with a 3 1/2" collector. I talked to Dan Lemons quite a bit and he indicated that his BB header was designed around the DSE 600 steering gear, etc... and will not interfere with any accessories (A/C, etc.). I couldn't find any other manufacturer that sold a 2 1/8" setup that would work with all accessories. According to Dan, the collector flange is designed with the 3rd bolt facing upwards to maximimize ground clearance, with the bottom of the collector dropping no lower than the oil pan. This wasn't a cheap purchase, but why skimp now?!
Here's a photo off of the website:

Now .. I need to decide what 3" system to run behind these puppies! Flowmaster Super 40's, Magnaflows, or Spintechs?? The car is not a daily driver, so slightly obnoxious is ok
