Fiddly to remove air box, but doable with a small 1/4 inch drive socket and extension for those 4 bottom nuts. If I recall, you may be able to get at some with a longer extension from above, but maybe 1 or 2 will need a short extension accessed from the underside.You have to feel for the nuts, and you are bound to drop some nuts and washers along the way. When you put them back, put a second nut inside the socket.
I think people have removed the air box together with the carbs, but probably even fiddler...Lots of 16th turn work for the hardest to get to nuts.
You will need to detach the carb support which goes down to the engine mount, and that is harder with the air box still in place, the carb earth strap, accelerator pushrod...
I considered this approach, and even started to do it once, but on balance found it easier to get the air box out first....much easier to then see and reach everything else.
Adding in the manifold to the equation....I don't think I'd attempt that myself....too far and harder still to reach the nuts with everything in the way.
And you can indeed take them all off with the head. Others may in fact say that it is indeed easiest overall, but you still have to get at and disconnect some bits by feel. I've not done it that way.
Have a go at the air box, you may be surprised. You pretty much have to hug the air box to find/collect/replace the washers and nuts underneath. Lots of visualising and sticking out your tongue is required. A light and a mirror will help you see what you're up against, plus a magnet to catch bits, and help you decide which way you want to go.
Third or fourth time you do this will be a snap.
