tight fitting header recommendation

So i'm putting my 414 into an off-topic ex-drag car (gasser) to put back on the street and piss off the Ford/Chevy crowd. I'm using front and mid plates and looking for a set of headers that are full length, good performance, but tight to the engine/trans. They can hang down, but they cant go wide since the frame rails are only 26inchs inside-to-inside. (anyone know the width between A body rails or can measure for me?

The engine does sit up quite high- the pan rail is only 2.5 inches below the frame top.

Yes, it would be easier to go straight out and up, through the shock tower holes, since the towers were removed in the 70s, but then it would be super tough to go between tire and door jam, then manage to get an X pipe involved to avoid sounding like a tractor., lol. I'm aftraid i'll be in that home made fenderwell camp, but really hoping you guys know of a tight tuck that is a real 4into1 instead of block huggers that will choke me off.

TIA
Rick
