2 - 1''Row Alum rads Any good

I am putting a 440 into a 69 Dart . I am see these 2 row alum rads with "true" 1''tubes that claim to be better than 3 or 4 row rads. Anybody running one of these 2 row rads ? The ad is all over this web site. Naturally , on a budget. Any rad ideas ? I was going to use a 26'' rad and want to get one large enough for NO overheat issues.
Thanks guys ,
