The noise supressor was definitely not put in there by the factory -- it was from Radio Shack

I don't have my shop manual handy, but I think that the original plugs called for in the manual (for the 430) are Champion F11Y. As you said, not a resistor plug.

I'm using AC resistor plugs and resistor wires.

I have a box stock 1958 radio. Works great (for a 1958 radio, anyway). No noise of note.

Since I have had the car I have scrapped the stock wires and plug caps and put in metal core wires. The plugs are standard Autolite ( Y 45?). No attempt at noise suppression at all.

The radio works fine - but if you open the hood all hell breaks loose, which reminded me of the significane of the metal body in noise containment. By comparison I have friends with fibreglass body cars (Vette, Avanti) and their ignition systems are enclosed in metal boxes to do the shielding.

Do the Tbirds have a ground tab for the hood from the firewall to the hood? I haven't gotten far enough with mine to really worry about the radio, but if the hood is not a good ground plane you'll get RF noise from the engine to the antenna. Also, make sure that the ground is good to the radio chassis and the antenna at that end. My noise problems have almost universally been ground problems on other projects, including the space shuttle.

Yes, there is supposed to be a ground tab that connects with the hood when closed. The section in the Shop Manual about the radio shows where it is.
