The XV is almost exclusively for forced induction, it absolutely sucks for naturally aspirated. The 6.1L manifold is better in the top end, but bear in mind that the 4th gen active runner intake manifold performs better across the entire rpm range compared to the 6.1L manifold. Unless you're planning to run big boost, you'll see the best results from staying with the 5.7L truck manifold.

That Brenmar manifold has been in development for a while and they have had 'prototypes' floating around for the better part of 2 years... until I see them up for sale and physically on vehicle I wouldn't spend my money on one. Those numbers are also comparing it to the static LX manifold on the pre-eagle heads. It's been on the LXF for a while.

Now, a swap that I would contemplate is a 6.4L active intake manifold. Best of all the worlds and it's port matched to our heads already.
