SC head differences - explain

I see on the Pelican catalog pages that there are 3 heads listed for the SC 3.0 na

930-104-029-08 = 1978
930 104 028 03 = 1980
930-104-028-05 = 1981

What are the actual differences in the three heads?

Also, the heads that were recently removed from my engine have a casting number that does not match any of these numbers. Maybe casting numbers are different from part numbers.... but my head has 930.104.328.3R and on a different flange is cast 7-81. I'm guessing these are 1981 heads. Are they considered good, average, or ?

Thanks.
