Shorty headers??

Has anybody tried them on a A-body or B-body? My car is not a rat rod (which these headers are often referred as). The ones I'm looking at are the Hedman 78500 shorty headers. Do you have to use a mini starter? I've used full size headers before but on this project I don't want full size (under body) headers. Too much around the starter and steering arms.
The shorty headers, at least I would think, would easily outflow the best of factory exhaust manifolds?.?.?.
