Which Vintage Head, and Why??

Sorry about that... '70 Dart, It's a 150,000 mile 225 /6, 1 barrel intake, and stock exhaust on the vehicle now, so I'm not really looking to burn off the tires... yet.
,It's getting a little tired. Some one just gave me a peanut head, albeit one that is completely covered in crud (inside and out), and I also have the original head I took off my '63, and the '70 Dart head on the car. I have a 2 barrel manifold laying around on the floor, and have been admiring the Dutra Dual system as an excellent solution to the exhaust. But which head is the best? of the 3? is there another vintage even better?
