I will call SD for heads.

You would be suprised how much better the big tube headers can fit on some cars.

Though often one tube on each side gets re-routed around/over a frame rail to make that happen,and the primary tubes themselves are a "slip fit" into the collector,also these sorta headers typically use a sub-flange on the head that repositions the flange bolts,so that inturn eliminates the hassle of trying to get to "that bolt".

Most folks that use these sorta headers swear they'll never go back to the "traditional" style of headers.

I'd likely be talking to Mark @ maddog myself.
