Tell me about it!! I learned the hard way too... had engine fully built, took it off the engine stand to fit the flywheel and it wouldn't go on... so engine apart, crank out, off to get machined, rinse and repeat.
Something to do with flex plate / torque conv / trans being a VW unit....
I checked the two cranks I have in my shop at the moment, both look like yours and the flywheel goes on fine... but check yours just in case.
BTW just noticed your water pump, thats the cast iron housing as per ritmo/strada type pump... that's why the gasket was wrong, Chris supplied the correct gasket for a "regular" sohc... I like the pumps as the impeller is the most effficient, but dont like the housings 'coz they are heavy... if you've got A/C then it could be what the late A/C X19's use in north america???
