There looks to be a bit of corrosion around one of the combustion chambers but it should be repairable. I've seen worse.
I know of engines where it has been almost impossible to separate the Alta head from the block.
Its a pity that the rocker shaft assembly is missing, as I have the rest of the parts....although taking a chance on the lack of corrosion from a picture is risky....can be very expensive to fix....
