All depends.

Most guys convert the end (secondary) carbs over to the improved thick throttle plates and block off the idle circuits. The thick plates allow the plates to fully seat without any idle air flow and still not stick closed at idle.

But, a few guys run the stock idle circuits to make up for the "leaness" of the small air leak at idle if using the stock throttle plates in the end carbs.
