Default 400ci Guidance

Trying to get some verification on my Dart 400ci block. On the rear of the deck by cylinders 7 and 8, there are two holes. My heads have the same holes but only one side will match up. The heads are identical but one side will plug the holes.

Hard to explain but here are a couple pictures. I’m just not sure if them being block is a problem? Thanks in advance.

I have some Dart heads and have talked with them several times by calling. They have been very helpful.
