Block stamping thoughts?

I have seen a lot of BB stampings that are directly under or underneath the head plug. The all “claim” to be original stamps. I am not sure how this could have been done.

Tonawanda stamped the deck prior to the heads being installed.
"The engine suffix was stamped on the deck before the heads were mounted (at least for BB's....not sure about SB's), which would explain how some stamps can be so close to the heads that would otherwise make it impossible for a gang stamp to reach."
