Special thanks to SteveHose and his thoughts and ideas for my Weber tuning. After a complete rebuild and new linkage, they're running better than ever! I'll post my current jetting set up soon for anyone interested...
If you think you're happy now, You'll love this.Next on my list is a 123ignition distributor.
Those holes on #4/#6 intake runners are threaded but they're not through holes. Just tapped for linkage risers. I decided to pull vacuum on underside of #3/#4 - we figured those are opposite the firing order to balance the pulse. Capped now but will use them with 123ign and an anti-pulse valve (per your suggestion!).
Brendan, you got it. How about this deal, I'll even let you drive it but only if I can drive your friend's McLaren!
@Stevehose: Yes, definitely need to ditch that vent. Already getting gummed up! Would like to see if I can pull some vacuum on that line through a catch can but I don't want to push that dirty air back through my intake. Anyone doing this sort of vac? Seems like that would create some add'l efficiency.

Are there versions of 1-2-3 that can take a TPS input?
DCOE TPS's and not expensive and they will give you a clean electrical signals at is related to manifold vacuum.
