I just wanted to see if I'm not some sort of dinosaur where there was some magic potion being sprinkled on these 4 bangers that would make these gains plausible.

The reason it doesn't make sense is volumetric efficiency. If Toy is artificially restricting it that severely from what it's normally capable of, not talking any special sauce, just regular flow into the head, then you are lugging around a whole bunch of extra engine everywhere that you don't need, impacting efficiency significantly. Again, it just doesn't add up.
