Pics on their way shortly.
In the meantime, having cleaned everything up I have found-
Crack in the block. Between the centre inboard middle head bolt (if that makes sense) and the water jacket, right bank.
Damage on the sealing area of the block for #3 cylinder. Meaning that for a section the 'fire' ring, the actual seal is performed by a area only 2mm wide, and 20mm long, with the damage going straight into the water jacket.
2 other cylinders have a small amount of damage similar, but not as extensive.
In the right hand head, #2 exhaust port, signs of porosity.
And a few clues that this has all been apart before, and hastily put back together.
Not a day for celebrations
