This aint the best picture, but I think "tall lid" may have been misleading depending on the year or air cleaner, because this 79 which has a a half-Qjet (Dualjet) and Im certain that the 260 oldsmobile its on didnt need any high tooting lid for the air filter, lol, but the filter visible to the right is rather tall for what it was stuck on and the lid wasnt all that tall lookiing when it was over it.
This 1980 with a dualjet on a 260 oldsmobile has the same base air cleaner, it seems, but it has a "short" lid

With the filter youd expect under it. The air cleaners dont look different from quick shot, I should ptu them side by side and show what I mean if I remember. But I think the depth of the air filter around the carb can allow a taller filter without the lid having to be taller, if that makes sense. So a small rise over an already normal filter size lid may not be super noticeable and surprise you, but if you slapped the 260's dualjet on a SBC manifold and threw it on the truck
you would prob have issues with the distributor or something else, maybe. The 400 pontiac air cleaner I have sits almost flush with the top of the carb so the air cleaner wall is tall, but the lid is flat.
Maybe the best way to look at it is, has over the years and the various applications youve seen filters, have you seen taller filters used where you wouldnt find a short one, regardless of the air cleaner design
my dads 75 400 air filter seems to be taller than what I would expect, but the manifold was a high rise manifold, so maybe it had more "drop" around the Qjet?
