Rev limiting vs non-rev limiting rotors

The PO had put a rev limiting rotor in my 1980 SC, which was unneeded. I got a new non-limiting rotor and cap. My question is...

The Rev limiting rotor seems to be slightly offset where the probe electrode is, vs the non-limiting one. Therefore, if I put my cap back on the same way, the rotor will be slightly rotated from where the old setup was.

Does the distributor now need to be clocked for timing? Does the factory CDI unit fire a long enough spark that it will hit the electrodes in the cap anyways? Can I simply rotate the cap slightly, or do I need to actually rotate the distributor body? Engine starts and runs fine after the install, no stumbling or coughing, so I assume the timing is fine.
