In looking at the JBA, that might be the best bet aside from fabbing my own.
JBA's shorty header:

But I've got concerns that the big triangular flange they use won't clear the frame rails.
The other notable are Flowtech headers:

While these are a good efficient equal length design, the tube routing makes them pretty large - I doubt they'll fit the space available also.
The JBA looks pretty good - I just need to make sure it doesn't stick out from the head too far. I can always change the collector flange if it gets into the frame rail.
