I don't know about the later models, but my 73 454 and my current 83 454 both used standard V8 truck radiators which were 2 core, but they were thicker than most radiators. The one I currently have in the 83 came from AutoZone and is a thicker 2 core aluminum and plastic one from Spectra. It cools fine in the 100+ degree desert heat. I have given up on copper/brass radiators.

Personally, I would stay away from headers, since the BB takes up a lot of under hood space as it is, but I know a lot of people like headers anyway.
