Converting to carburetor

...and I take back what I said.

I clicked on "Return Policy" at the bottom of the screen and found and address and phone number.

The carb idea is not great. It will surely be more work, money and headache than finding your problem.
As for the heads, you have already done mediocre heads once, now you are going to risk it again on an unknown set?
IMO, buy AFRs or Twisted Wedges and never look back.

I'm gonna jump in here, against my better judgement, first won't rev past 4k, I doubt that it's an electrical issue, valve float that starts at 4k rpms could be lifters starved for oil pressure, rockers too tight/loose, fuel starvation, timing, valve springs. Sure I'm missing a couple things.
Installing aftermarket ignition boxes, a carburetor, different heads, programmable ECU likely will make diagnostics more difficult, sure you may stumble into fix'n it but highly doubtful.
Oh, and the 3 bar heads have a bad rap, they are really good upgrade for a stock street cruiser, just a little boost up from stock,.with the right parts,
I'd go back over my assembly procedure and recheck those things.

The one thing we agree on:

It's better to find and fix the issue before throwing more at it. It [should] run like a top.

I'm starting to lean in this direction though when it happened to me it was sporadic and not like [rev limit] feeling.

The shop that has done most of the cars in our club (Foxbody Club Of Connecticut) recommended these heads. They’re basically AFR heads without the price tag. The one time I didn’t listen to them is when I used the GT40 heads. They told me not to, but NOOO I did it my way.
