Shorty Hedman Headers

have them on my 360 71 swinger w/ good ground clearance also a mini starter, the worst think about the exaust is reducing at the header to sumthin like 2 1/4 then bending and twisting it up to fit. tti has what seems to be the best out there. does any body know if those dougs headers really fit the sb a body they run 380 for decent looking headers.
