If you turn the carb 180°it will tell you if it's it or the engine causing the maldistribution. (Or of course trying a different carb.)

That’s some good gains with tuning. Did plugs show the rich and lean spread before you stagger jetted?
Plugs really didn't show a lot, they did look cooler on the front but not a massive difference.
EGT's were almost 250 deg different front to rear, 1350 or so on the front, 1100 on the rear. That was all 4 front hot & all 4 rear cold.

Gotta be carb!

No fuel flow details, didn't have that hooked up, it's a bit of a PITA & the headers already gave us sh|t fitting up, didn't get it fired till 2pm & finished up at 9!
