Can you change big ends with heads in place?

[ST00]

Daft question I know but is it possible to split the crank case with the heads on?
I'm 95% sure it can't be possible but I'm wondering if anyone has any dodgy techniques.

Also now the engine is out and stripped to just block and heads can anyone suggest a good garage to take it off my hands and do it for me within 2 weeks?? (I'm in Surrey). I'm fairly handy with a spanner after building a few mini engines but I'm so short of time and it needs to be finished by 18th July for our holidays!!

After reading all the doom and gloom of the water boxers on all the forums I'm kind of getting put off DIY. It should be easy. The engine's only done 27k and still got lovely clean oil and pink antifreeze so I'm hoping all the internal bolts aren't seized. If guessing the bottom end is gone due to some rubbish getting in the oilways from the rebuild. Everything else seems OK.

I' m on my third wbx rebuild at the moment and as a man who works very few hours ( according to my wife ) and spends too long playing with cars ( according to my wife) all I can say is that to properly clean and collect the parts to rebuild a wbx takes many many hours.this last engine has been apart for a week now and apart from cleaning and assessing the crank and cylinders the only other work I have got done is to partially clean one half of the crankcase ( still needs about 3 more hours ) To answer your question no you cannot access the big ends with the head in place and to rebuild your engine before your holiday will take more hours than you have if you are working
