decided to remove head anyway, bores look perfect, although i can only see 2...if i'd thought , i would have tried to have all pistons down halfway, to see upper parts of all bores
rocker cover studs were really tight, bent them getting them out
didn't spot the "hidden" water pump bolt until i'd got the hammer on it a few times!

questions....how can i tell whether i've disturbed the liners, as they're so well located?
....do i really need to bolt them down, as the head won't be off for long?

incidentally, bores got water in, as i hadn't drained down enough, but a good powerful hoover out with a pointy attachment gets any crud/water out, if you go round the edge of the piston carefully

also, got heater valve apart...needed to grind off retaining screw (will fit roll pin in place)

now, just got to buy all the gaskets etc, do a head skim etc
 
More possibly than not the liners will be rusted solid in their locating bores, after so many years. If you haven't turned the crankshaft so far they will not have been moved.
As Steve said, bolt them down (some short M10 bolts plus sufficiently large washers). No need to tighten them excessively, just a little more than finger-tight. Now you can safely turn the crankshaft and chack / clean all cylinders.

thanks for that....now, another question...the holes in the water distribution tube are not 30 deg to vertical as stated in Haynes, but more like 75 deg, meaning that they're not "firing" properly at the lower part of the combustion chamber, and i can't seem to shift the tube....should i worry?...or, any tips on moving said tube?...Adrian
