New engine mounts, bolts loose?

Kind of a strange and very specific question.

Im at the stage of my restoration where I’m putting the small block back in. I’ve got new replacement clamshell style engine mounts on the frame.
The long bolts are 7/16”, and they fit very loosely in the holes of the rubber isolator part of the new mounts. I can even get a long 1/2” bolt to go through and even then there is a bit of slop between the hole and bolt.

Did I somehow end up with the wrong mounts or improperly manufactured mounts? Or are the bolts supposed to be a bit loose in the mount to allow the engine to move around slightly? I don’t have my old mounts anymore to compare and I’d like to figure this out before the engine goes back in.
