1968 Dart 270 NON-build

Looks good, I bet a borgeson box would give you the header clearance you needed without denting tubes, and speed up your steering ratio.

I agree. Or a fast ratio manual box. Both are an an expensive solution to avoid denting $175 headers. Even if I replace the 273 with a mild 360 one day, I don't think the clearancing will hurt performance much.
