This issue is more common on Holley modular carbs than many other makes, simply because of the two separate fuel bowl volumes, one each for primary and secondary bores.

Accelerate hard, g-force allows the fuel in the secondary bowl to rush to the rear of the bowl, AND allow more fuel in. (The Primary can act in the opposite manner.)
Get off the gas abruptly and the momentary high fuel level rushes out of the booster venturis, flooding the engine rich.

The OP has stated the engine runs rough after restart, and then smooths out.

I would like to know whether the exhaust blows any puffs of black smoke on restart.
