Here's the procedure from the service manual (paraphrased)
1. Turn the engine till #1 intake valve closes and continue turnig about 1/3 turn till the #1 piston is at top of the cylinder.
(the manual says this "This can be determined by watching at the timing indicator opening on clutch housing above starter until U/C marking on flywheel lines up with pointer.")
2. Install the distributor into the block with the distributor cap spring clips parallel with the engine block, turn rotor slightly clockwise from 90 deg to engine block and push distributor down into position. It may be necessary to remove the distributor and use a long screwdriver to turn the oil pump shaft to align the slot with the tang on the distributor shaft.
3. Turn distributor body slightly until points are just slightly open and tighten distributor clamp screw.
4. Install cap and check that rotor is pointing to #1 cylinder.
That should get it close enough to start.
