7 Engines what have I got?

Ok I bought a beetle awhile back and it came with lots of parts including 7 engines I will list them below and would like to know what you think they are and if they are worth keeping rebuilding?

1. 9700113
2. H1258263
3. AD633030
4. 9057284
5. 6470 thats all that is on this one WTF?
6. F0126058
7. H0999735

Feed back is appreciated thanks guys.

Heh... you have 7 Volksy engines !!!

F's are 1300's
H's are 1500's
AD's are 1600's

That's what they would've started out as originally at least...

hey thanks any ideas what the engine is with 6470 number only?
