New heads on the way for my Dart, few changes

who knows, lol…not gonna spend a grand to find out at this point regards headers.
Just want to see what these pick my car up…and i now know i have enough head to support 9 sec passes if i ever decided to do it( very unlikely to do that again at my age)…but the potential is there.
I never upgraded to a Dana, just bought fresh nodular case Moser 8.75 centersection last summer.
So thats the other thing, keeping it in one piece till next off season, and footbraking only..i actually went about this backwards..not a first for me..i can be mighty dumb
I dont know the seller and this is not a for sell add. But I saw on moparts for sell section that somebody had some Headman 1-7/8 A body headers for around $500 i think. Also I look forward to see how your car runs with the new heads
