After all you've done, it has to be either spark disintegrating or fuel leaning out once the secondaries open up. Problems only seem to crop up when you go to wot. I'm ruling out a broken valve spring for now.
It's going to be something simple, you just haven't found it yet.

I wish I had a dyno. The only one I know of is over in Dallas. I'm just about to give up and take it over there.
I didn't see anything in the jets when I took it apart. I'm going to check the fuel pressure with the GoPro. If that's fine, I'll disconnect the secondaries' linkage. If I can go WOT with just the primaries, it is the secondaries circuit. If it still stumbles, the primaries are involved or its the ignition failing at high rpm.
I've had the valve covers off. No obviously broken springs.
