Junk yard manifolds...?

Hey guys been awhile since I have posted, but anyways car is a 1974 Dart Swinger with a 360 power steering, power brakes, and auto transmission. I have Headman tight tube headers but they are so tight to the block on both sides it's impossible to get the collectors bolted up tight enough to hold, forever leaking.... Anyways I'm getting ready to pull the motor and trans to fix other problems, I'm to the point I just wana put manifolds back on, is there a combo from the junkyard that will work on my Dart? I know there has been posts about this before but I couldn't find what's I was looking for, any help would help guys.
