Dougs headers vs. patriot exhaust

I'm going to put a set of headers on my 360 which is going on a 71 dart swinger with power steering and a 727 trans. The Doug's headers say specifically that they won't work with a 727 on the column. These patriot exhaust headers seem very comparable to the Doug's, and say they work with my transmission. Anyone have any experience with the patriots? Or does anyone know how to make the Doug's work?? Thanks.
