74 Dart. Headers vs manifold.

TrailBeast said
What you will go through adding headers will end up actually making very little difference.
In your specific circumstances I would try and get something like the FItech fuel injection because you need to get places regularly with decent gas mileage.
I'm not just throwing fuel injection out there for the fun spending someone elses money either, just in case that crossed your mind.:D

Hmmm I see well I just bought the 4 barrel carb so I kinda have to stick with that for a while ($$). One of my exhaust manifolds broke so I’m having a little trouble finding another and I was advised of getting headers to improve everything and how it was overall beneficial to the car
