You have just got your own crank reground, meaning it is within spec.
The small marks / groves it got from the broken lifters is easily polished down to a useable level, giving it a long life.
People that races high tuned V8s just polish their crank if it is within spec.
If it was me. I wouldn’t use the crank in the picture. I am sure someone had done the holes to lighten it and by that is is also severely weaken.
You don’t even know if its now severely out of balance because of the drillings!
The original VW cranks were balanced when left the factory, without the need for those big holes.
Your old crank works.
This one you don’t know if it will break shortly after you have assembled the engine again.
Play on the safe horse , and don’t take the chance.
