I cannot locate said pictures. Am I being stupid?

I am not quite sure what you are talking about....
Is the measurement you are talking about from the inside of the crankcase to the outside of the main bearing?
If so, then I'm not too sure that it necessarily means too much anyway. But I am not 100% sure here.

If the lateral play between conrod and thrust washers is OK (0.55-0.75mm) and the anti-spin pins on the main bearings line up with the slots in the cases, then you are probably OK.

Pictures or better description required really.
I am guessing that you don't really want to take the barrels off to check the lateral play of the conrods. But perhaps this may be good for peace of mind?

<edit>
Oh, I think I couldn't see the pictures because I wasn't logged in. D'oh!
So you can basically ignore what I have said here.
When pressing the cranks back together, I would put put a couple of 0.65mm feeler gauges in place to ensure correct lateral play.
