Nickel plated copper bars.

Yes, of course. Bare copper oxidises. However, I mentioned bus-bar as
an example only to indicate the case where it would be necessary to
bolt the PCB to the fixed conductors and that even when using cables,
the same mounting method would apply.

It might also be advisable to use a conductive jointing paste between
the PCB pads and the brass terminal blocks to aid in maximising
contact and preventing any electrolytic action.

I do not need to measure the current. I need to deliver it to the PCB. This
is for a electric furnace control board. The six elements will be switched
with individual relays. It adds up.

I would think that for many reasons, feeding six "htos" to the board
from a bus bar would be better than one huge cable and splitting it on
the pcb to the heaters. Cost -wise, probably cheaper. Installation-
wise easier. If one feed, one bad heater could not be detected, a
shorted one could take them all offline. Etc. Etc. Etc.

My customer desires to secure #0 or #1 gage stranded copper wire to a PCB.
Other than striping the insulation, it is desirable that no other
preparation of the wire is permitted. Is there some kind of approved
transitional component that can be securely fastened to the PC board,
provide a good interface to the copper pour on both sides and be capable of
handling such heavy wire?

You could take a look at Anderson's Power Poles. Their direct PCB
connectors only go up to 6Ga but they do have a bus bar that does go up
to 1, see the PP180. However, I don'think it fits your minimal prep
requirement, you'd have to crimp a pin on to the wire.

void _-void-_ in the obvious place

I cannot find any realistic use for bonding such a large cross section
conductor to any PCB for any reason. In part because i do not know of any
PCB that has equivalent cross section traces. Give the PCB a break, you
are in copper busbar territory.
