Does the engine flat spot when this spike occurs?
If the engine responds well I wouldn't worry about an A/F gauge spiking like that.
Have you got hollow squirter screws?
The Holley 850 XP/HP is known to be lean out of the box, I would think about a better carb, like Pro systems or one from Troy Patterson (TMP Carbs).
