It looks like the cam is from a later model VVT.
It is not uncommon for the build date and title to be off - it's just an Alfa thing.
There's virtually no difference between a '77 block and an '80 except the number. By 1980 the Spiders were pretty doggy performance wise. They may have swapped motors to get a bit more although a '77 wasn't exactly a rocket ship.
I would suggest getting the CarDisk CD (Centerline Alfa I think) which has a ton of useful info including the Alfa Parts Book which is where a lot of those exploded views come from.
Good luck - more pictures!
