Pleasingly good condition. The deck has no corrosion, the marks you see in the usual corrosion spots are surface only. I think once skimmed you can expect this deck to come up immaculately.
In the chambers note also that at some point someone has knocked the corners off the long side of the chamber recess.
I hadn't taken a closer look at this head until now but generally it looks to be in great condition although my advice with used heads is always to tear them down, resurface, lap the valves, replace the seals.
