IXB block value

[DaveInMI]

I saw an add for a cracked IXB block.  I have one cracked and another that has worn past .060.  Do these things have value beyond scrap value?  I have an unknown IXK complete and stuck.  What do you think it is worth?

Where is it cracked? How are the valve seats and guides? Cylinders can easily be bored and sleeved. I guess it mostly depends on where the crack is as to whether it is savable.
