Engine identification

[desmo2]

Hi , I need a gasket set for an R80 motor I have . Seems like there are two available ? One for a 1978 and another for 1979 0n .
One of the sages here gave me a link a while ago I think to ID a motor from it's engine number . Could someone please do the same ?
Alternatively , what's the difference in between the two gasket sets ? I could possibly take it from there .
Thanks in advance , Mike
