Header fitment for a 69 dart 360

I've always had cheap Summit headers and they work fine... When I upgrade I upgrade to the cheap Summit ceramic coated headers and love those as well...
I've never scrape the ground and I've never had a problem putting them in...
I do put them in during engine install though so I've never tried putting them in with the engine already in except for once about 20 years ago and it was not that fun... it was not that fun enough to remember to do it when I'm putting the engine in...
