Question about the hole under primary ports.

Vhat is this hole? I bought my car with european but broken engine.
The only engine i could get was from USA. I swapped engines but i used all the parts from the european.
The intakemanifoild of the european Did not cover this hole.
However on the USA there is a channel on the manifoild from this hole whitch goen into the carburettor.

Is this a exhaust EGR hole thing?

The hole is the EGR hole. It connects to the EGR passage on the top of the iron.
