what brand headers are these?

tHESE HEADERS I PURCHASED FOR $50 from a friend, he said they were mac. they did come off a 5.0 87-93. they have one complete flange not individual flanges per tube. So are they not mac headers? the only thing they have stamped is a 6 digit #117-701, what ever that means. who makes this header just so i know?

MAC makes $hitty headers. They are individual flange, so if yours has a single-plate flange then they're probably BBK. BBk makes decent priced products that work well. What color are they?

i have BBK shortys and they have a plate stamped/welded on them that says "BBK"
