Point em' toward the crank bores. You should be able to see em' line up by looking through the crank oiler holes. It's been may may years since I've installed cam bearings, but I think the (2) hole one goes in the back and shuld be a little wider?????? They should be numbered. If my memory has failed me sumbuddie' will correct me.
the wide rear bearing with two holes is used in the early blocks 55-56, 57 and later went with the more common one hole that is more narrow.
