Holley stumble trouble

No reason not to try to get the most out of it, right. If I get to the point of madness dealing with this stumble then I’ll surely just disconnect the vacuum pod and continue mission.
I guess you're kind of making my point in getting the "most" out of it.. I'm pretty sure we're not building any of these performance cars for gas mileage? But good throttle response would be Paramount I believe... after that I figure the gas mileage is where it is and if I wanted more I would consider that part of the performance compromise...
