No one is arguing that the turbo inlet manifold won’t fit, it will bolt straight on. That’s got nothing to do with head port size.
The ports are smaller on a de neo head. There’s even a picture that shows that.
It is definitely worth pointing out to people the ports are smaller, not sure why you are cranky about it?
your argument is odd in that you are bashing people for not “adding anything” but all you have added is misinformation.
the ports in the de neo head would have been kept smaller to keep the air speed up for better efficiency. Still going to work with a turbo, but those smaller ports then become a restriction rather than a benefit when making some power
