Front Drum brake troubles on a 1964 Dart

Yeah seems pretty straight forward except the drums these days aren't as heavy duty as the New Old Stock drums, they're light weight, out of round, they're warped straight from the chinese factory, and that's probably why people switch to disc these days. But with this ride I'd like to keep it stock with the 13 inch wheels and original hubcaps. I have discs on my 63 Dart wagon kustom and just want to try something stock for a change.
i feel you on that, and a change to the rims and tires is a serious cash outlay.

have you considered sourcing used drums and having them turned? they pop up frequently here (and in junkyards) for relatively cheap.

i'd start with making sure everything is absolutely to spec and installed correctly from the backing plates to the lug nuts.

has other work been performed on the brake system? sometimes a change of component can have detrimental effects on other parts of the system.
