327 main bearing question.

Helping my friend with his engine assembly after a camshaft problem. He ordered new bearings and on the upper main bearings the oil hole doesn't line up with the hole in the block. These are sealed power bearings with one hole up on the side of the bearing and a groove with a slot in it.

When looking through the groove with the slot cut in the bearing you can see the oil galley hole in the block. Is this okay? Looks like it would restrict oil flow to the mains?

His old bearings were Clevite with two holes in them. One hole lined up perfect with the hole in his block the other didn't and is in the same location the one single hole is on the sealed power bearings.

This is in a 1966 327.
