If someone wanted to call the Flying Aces loop inverting, I wouldn't stop them. The heartline entry looks nearly identical to B&M wing coaster dive drops, which we do consider an inversion.
As for tallest loop - well we only really track tallest vertical loop (currently Full Throttle at 160 ft/49 m). If Ferrari were to consider the loop an inversion, they could actually claim it to be the tallest inversion in the world (tying Gatekeeper, which also measures 170 ft/52 m).
To say it's the tallest loop? Yeah, you could qualify that. I just get the feeling that there is a very purposeful reason to not call this an inverting loop, as the case could easily be made otherwise.
