Tuning a Proform/Holley carb, what parts and tools?

Geeze just watched the video. I'm trying how to figure out how you have wet, black plugs and have a fuel system that has a delivery issue.

In that case the plugs would be white were that the case.

As for carb choice it wasn't size, it was that carb. I don't remember if you posted engine specs, but it wouldn't have been my pick for anything with much cam in it. That's what I meant.
