B main bearing problem

Installing new main thrust bearings on 45 B.
Noticed that the oil hole in left main bearing doesn't line up completely with hole in main bearing housing.

Main bearing housing cast number is b2040r.
Is it better to make hole in housing match bearing or make hole in bearing bigger?

I don't have part number of bearings.
 
What did your original bearings look like ? or are these the originals ?

Maybe you have the wrong bearings ?
 
I guess if you feel they are correct and you can't get any like the originals then I'd think it may be easier ? to match the bearing to the housing.
