340 oil galley question

...did the factory rely on the cam thrust plate to block off the oil galley? It does not look right to me. Any help would be greatly appreciated .

Thank you,

The factory did rely on the cam thrust plate to block off the oil galley in the early engines. I've done a lot of engines without the plugs and no problems. But I agree with 1wild&crazyguy, to put the plugs in for cheap insurance.
