I was going to install the no 8 main and re-mic the bores, but the bore gauge wont fit thru the small bearing id, so i took your suggestion and plastigauged the bearings. All checked good, so i'm a happy camper.
There's lots of old junk #8 bearing housings floating around so next time you can have one of those bored out to allow your measuring of the bores. Or cgarr has pointed out that there's a VW air cooled case bearing sleeve that can be used as well, since it has the same OD as the Porsche #8 bearing insert
