Are these cylinders junk or is there any hope of saving them?
Don't know much about chrome cylinders, but if the environment was harsh enough and exposed long enough to make the chrome separate (not easy to make chrome separate from base metal), I believe that you need to pull that engine apart and check everything. It may not be the full extent of corrossion issues.
Don't know about the spider cracks though I suspect that is enough to red flag them. If the chrome has separated from the steel, they are definately no good. Though they can be overhauled and re-chromed I believe. Not sure that is much of a savings over new these days.
