Ebay GT45 + 5.9 Magnum + E85 blow thru

"What headers" are they? By the way I did this back in the 70's putting a 340 in an old FJ-40 Landcruiser. A833 with (crap) advance adapter to straight through Jeep transfer case
I will get the info off of my Buddy tomorrow. He's coming over to work on getting my engine out of my Dart.
