70's cb550 carbs

[metalheart28]

I have a set of rebuilt carbs for 77-78 cb550k and had a guy ask if they would work on a 74, I couldnt find anything definitive so though I'd ask here. Any help is really appreciated!

"The Honda CB500K / CB550K use four individual Keihin 022A carburetors (one for each cylinder) connected to a common mounting plate. They are a bank of all mechanical round slide carburetors with a dual fuel inlet and are controlled by a dual throttle cable set up (pull and push cable).
Note the CB550K3 / K4 (1977-1978) uses a uniquely different model of Keihin carburetors which only appeared on this late version of the bike, which have their own rebuild kit and throttle cables..."
and from this site I see the K3 and K4 used different intake manifolds:

CB550 1974-1978

and since this is Chopcult, need some photos of cb550 chopper stuff:
