Small block 340 factory inlet, what are these??

[Crash520]

Hi Guys, just took my inlet manifold off to install a torker II manifold for the EFI and found these in each plane !!!! What are they please?

is that the top of the intake, a spread bore design??
what's on the other side?

Below is how it should look. Maybe its a repair, or
some kind of trick to improve intake flow/power.
Maybe someone was trying to prevent fuel puddling.
Just guessing. Sorry.

they look clean, like they have not always been in there?

I'm not sure what's on the other side as it's oil splash shield is riveted in place, it's a Dec 72 built 340
