It all depends on how your distributor is indexed.
However it was designed to have #1 closest to the vacuum advance, or the terminal that is located counter clockwise of the vent cap.

Number one spark plug has a lead.

That is the plug closest to the front of the engine.

That lead should go to number one on the distributor.

Unless you pulled all your wires.

Firing order is 1-3-4-2

Under normal circumstances, both the vacuum advance and post one are located at the front. (9:00)
