A little more progress this evening.
I have taken the other head off, no apparent issues there, except that a rather large piece of piston ring dropped out of one of the barrels, about 1/3 of a compression ring.
I then moved onto separating the cases. All the bolts came undone (one of the top 13mm ones was missing), though the lowest, and rustiest 17mm nut did need a bit of heat, lubrication and persuasion to unscrew. The inner case bolts are also off, but work had to stop at that point as I got called away, so no chance to separate the cases or examine pistons / bores. At least no studs are broken.
Oil pump cover nuts seem to have a fair filling of red sealant
I did a rough check on endfloat. Showed about 0.38mm, even at the angle shown, which seems to be rather a lot beyond the wear limit of 0.15mm
