The 23" version of the 201-208-218 are the same engine.
If you can get a 230 type wheel it may have the correct pattern. I don't think there was a lot of variation in the day, and, given the age, it could have more than one pattern already. If not, it is a fairly simple procedure to redrill a flywheel for a new pressure plate pattern when needed.
With the 201 flywheel, and all else being essentially stock, you will need to verify that moving the PP closer to the T/O bearing does not create a problem...that small amount should be ok but take a good look at the parts as assembled and verify.
Yes, your 4-bolt is of the same pattern as the 8-bolt.
