220000 is an interesting number, according to the "official" records that would make it the first 750 MkV supposedly built in March 1973.
But of course, we know that is not true! :roll: 220808 - build date Nov. 1972 and 221296 - build date Dec. 1972 reside in my shop!
October 1972 seems right to me for 220000 and the first MkV 750. So, what cam was in it when you tore it down? It would not surprise me if Norton used up the last of the Combat "C" stamped heads before using the RH6 heads. But I would be surprised if they put the 2S cam in them due to all the problems they had with them.
Does your bike have the 5 plate 850-style clutch?
