Barry Grant modified Holleys didn't have "idle-eze" until he released his Demon carbs.

Jet extensions are only necessary on the secondaries since g force under hard acceleration may uncover the secondary main jets.
Can never be a problem on the primary since the primary main circuit under heavy neg g force (braking) is not operating.
