I think you are getting a little too worried over the wrong things here, I would be surprized if your cylinders did not have a little corrosion in the upper cylinders but the is likely to be cleared by the first few sweeps of the piston rings in start up and have next to no detrimental effect.
If you are into oil analysis you will see a spike in the Fe but as long as this stabilizes at the second oil sample this is also OK.
The fact that the engine has not been turned is the only positive thing, turning the engine in storage just wipes the oil away that is protecting the surfaces.
I would be far more concerned about the cam shaft corrosion but as the engine has not turned this less likely to be a problem.
Chrome cylinders may seem to offer some corrosion protection ( the idea of using them was from the US navy in WW2 ) but chrome cylinders are not without their problems and these usualy outweigh the advantages especaly in aircraft that get used regularly.
Now all that remains is for me to wish you a Happy Christmas and raise a glass of Mount Gay 1703 to drink to your good health.......... and that of your engine !
