I did my 850 a few years ago. Yes, big pain. But I have driven the car for 60,000 miles since then, with no issues.
I did not buy any special tools, I think I just used longer bolts and slowly pulled the two halves of the head together, maybe starting off with some longer bolts.. I used the same sealant I used on my 911, the orange Loctite one (574?).
The head is tricky, the turbo was hard to get off, the intake manifold is a basttardd, etc etc.
Do the timing belt, tensioner and water pump at the same time.
And don't lose any intake bolts. M7 oddballs.
