Thanks For info just got off the phone with Philip in Atlanta
Husler Division of Hedman Headers and they still produce the # 75110 which is for the 64-66 Dart so im good and these are offered in 1 7/8 with 3" collector so they should work for me.
they can make them with W2 flanges to per a conversation years ago. 1 7/8 is huge for a small block. wonder if they would throw some B flanges on for grins? :)
IIRC the AMC "dog leg" heads were fantastic stock heads.
