That's not the best picture... what brand of "copycat" metering blocks and main body did that carb come with?

Have no idea,they are pretty coursely machined.
Found shavings inside too............

If that's a ProComp-based copy, it could be either the metering blocks or the main body having restrictions in the fuel passages.

Try Holley metering blocks w/ the current main body to see if that cures the problem.

If the metering block swap doesn't fix it, it could be something like the downleg boosters haven't been sized properly to flow enough fuel for your use.

My (and I know it's easy to spend other people's $$$), is to sh!t-can the Horrey calb and put a proven unit on it, rather than expend any time & $ trying to band-aid the offshore parts.
