I bore TBs ...
... and include a new butterfly valve to fill in the new bore.
On cable-operated TBs, I assure you that the butterfly closes all the way.
It has a very powerful spring that keeps it completely closed.
The only air that gets in when the pedal is not depressed is through the idle control valve.

Here is a side-by-side picture of a standard non-egas TB on the left and a bored out non e-gas on the right.
Note how the butterfly perfectly seals the bore on both TBs.
