ThermoQ -2 questions:

That intake will not take a T-Q without an adapter. Do not try and dremel it out. Place a T-Q gasket on top , you'll see what I mean.

The 4 holes to bolt down the carb are not for a T-Q but for the earlier Carter carbs. The Carter carbs (all 4 of the 4 bbl's) have that bolt spaceing.

Good call - did not know that. I will delete that note from my comment!
