WHICH CARB FEEDS WHICH CYLINFER ON A 3,5 v8 WITH SU's

I'm about to try and adjust the mixture on my 3.5 V8 with SU's and seem to recall from a Morgan running the same engine that is not as simple as the carb of the left feeds the left bank and the carb on the right on the right feeds the right, there is a crossover. I seem to recall that each carb feeds the two outer cylinders on its own side and the two middle on the opposite side but I am not confident that I have that correct. Does anybody know? Advice will be welcome!

Looking to use a Colourtune to adjust the mixture, should be interesting as it is at least 40 years old and been lying at the bottom of a box since I last used it!

Each carby feeds the directly opposite two cylinders and the outer two beneath it.
You'll easily see it using a colour tune. On the fuel adjuster screws on V8 SU's turn them clockwise to richen the mixture and anti clockwise to lean it out.
I've run SU's on my 3.5 for years. I usually set the carbs until it needs some choke on a cold morning to run. This gets you into the ball park of about 3% CO.
I'd suggest getting this far and then visiting your friendly garage with a CO meter for final tuning on a hot engine. It will make a saving on fuel consumption.
