The service manual has the procedure, but specifies the motor brought to 6 degrees before TDC and the rotor position marked.

The bottom line is hold the pump with the distributor blade parallel to the camshaft and the punch mark on the gear vertical. It's on page 32 of the manual. But make sure the #1 cylinder is at 6 degrees BTDC compression. When you are done the drive should be slightly off horizontal.
