64 Dart SB Block Headers? yes/no

Center dump block huggers have zero chance of working. Since Dakota manifolds will work with some judicious grinding, perhaps a Dakota shorty header MIGHT fit but that's a pricey crapshoot. The biggest restriction in the stock manifolds is the ball connection for the head pipes where the manifold outlet necks down to 1 1/2". If that ball were removed the manifold outlet would be roughly 2 1/8" and there would be plenty of meat to use a gasketed 2 bolt pipe flange. If you want to try this, I have a set of manifolds I will send you to act as guinea pigs. LMK...
