Have you measured the actual clearance of each bearing to each journal?
That will tell you if you have a clearance issue (and if so, how bad) or some other issue, like alignment, burrs or bend in shaft (not likely).
if they are tri-metal bearings you would not want to remove any material from the bearing to gain clearance. I'd remove material from journal before that or look for other bearings that offer correct clearance.
Was preoccupied with bearing OD and making sure each was in appropriate place, I never thought to measure the journals themselves. Knew that they only come in one std size and that the block couldn't have possibly shrunk.. maybe I'm wrong?!
Could the bearings have oval'd going in?
The only real way to know is to measure journal to bearing clearance. Bearings could have slight ovality or be undersized slightly. Is worth checking bearings like this to see if bearing fits on journal before knocking in. If they have insufficient clearance before going in, they will only be worse once in or if knocked in slightly askew.
They had a bit of 'slop' when placed over the shaft outside of block, so figured they'd be ok when pressed in. Should have measured, but really don't know what I'd do if they were out of spec anyway.. There seem to be a few similar posts on TB http://www.forums.turbobricks.com/showthread.php?t=305685
Maybe the STD fit isn't the same for all blocks. This is a 1995 B230FB.

Yeah, they are - well, all OHC blocks, at least. B18 / B20 ones (cam bearings) are different.
Where did you get your bearing kit? They are usually fitted by align boring.
However the ones sold by High Performance Auto (aka OVO = Old Volvos Only) are pre-fit bearings.
@Major Ledfoot Kit was from KG Trimning. They sell both pre-machined and machined sets. Currently emailing to find out if I was sent the wrong one.

Tell us more about this "High Performance Auto OVO". Is there a website? Can't find anything about it! Just curious! Thanks!
@carnut222 I'm sure you'd know these guys. :)

Wow, they've been in business since 1976 and I've never heard of them...unbelievable. They must keep a very low profile! We were pretty much going with ipd 100% in the late 70s-90s...
