Anyone using Dougs D453 headers on Magnum heads?

Sorry MileHighDart,
I'm interested in knowing what these guys are running the D453 on such as model, year, transmission, column shift, floor shift, etc.

1970 dart 4 door custom converted from column shift to floor and an 833 tranny. 408 engine, manual flaming river steering box.
