Can Anyone Tell me about this engine?

birdmannn101
I am getting ready to restore another CB750 and all I have is the engine. I know it is either a 1979, 1980, 1981, 1982 or 1983 year engine. If I post a picture of the engine could you tell me what year it is or would I be better off with the engine number?

That looks just like a 1979. Or maybe it is a 1982. However on second thought it looks just like a 1980, but looking at it again I am just about positive it is 1981. Maybe you should just give us the numbers, since all the DOHC engines from 79-83 are exactly the same.
