Default Should I replace the water tubes?

I noticed my car had a small leak on one of the water pump bolts. I had a spare waterpump with a cast impellar lying around so I figured lets pull the water pump and fix the leak.

So old pump has a stamped impellar and the gap between the impellar and divider plate was huge. I cleaned the divider plate and made the clearance a bit tighter and started looking at the water tubes. So when do these need to be replaced?
One is stuck, the other came out by hand.

The block is a 67 400 by the way and has the 8 bolt water pump.
