Any one interested in the oiling mods I did?

on my 340, stock rods, there is a hole about 1/16th of an inch in the bearing where the two half bearing shells come together. It goes through side of rod by bolt. I think this is to oil cylinder wall. Do you think i should use bearings with or without this hole. Have clevit 77 now with hole, but was told i can get without holes.
Thanks gary
