Put new and old shells side by side, edges down, to see if they match for size and shape - are the new ones slightly out of round?, even if they are not perfectly circular they should be ok when clamped in between the casing halves.

  That's why I suggested putting the crankcase halves together, to see if it all drops into place! Chances are at some point since manufacture they have had had something on top of them that has caused them to open up a fraction, my guess would be something dumped on top of the package they were shipped to you in, bloody postal companies! But, provided they aren't creased (easy to spot!) they should be fine to use. I'm about half an hour from you (A little village 5 miles S.E. of Exeter) but due to health issues driving is out of the question at the moment, but if you're not in a desperate hurry I'm more than willing to hop on a bus or train and come have a look for you.

If I pay the bus fare, will you come and give me a hand for a couple of days  ;D

As long as it doesn't involve heavy lifting, 3 hernias are more than enough thanks!

Bryanj:
just reading a very early 750 manual and it states " when the bearing is mounted into the crankcase, the top of the bearing should be extended above the case  mounting flange by 0.0027~0.0039 in (0.068~0.098 mm) so you sound about right

Cheers Bryan, Feel alot happier now you've mentioned that!!!
