Old news....
You mean where a video was put out stating the LT2 manifold was worthless, then another video posted soon-after, six (6) days later, doing a comparison between un-touched 87mm TB and LT1 manifold, then a 95mm TB on the following manifolds: LT1 ported, LT2 ported and MSD ported, to come to the similar conclusion that has been documented? Meaning that the LT2 manifold isn't worthless and has it's place...
GM, themselves, tested, documented and put out tech info that the LT2 intake is the largest contributor to the power bump in the LT2 engine over the LT1... it does something and is not a waste.
Now, is it the best option? No! That's quite dependent on the application (engine build, car use, budget goals). Just like there is a reason to go with an 87mm TB over a 95mm or 103mm. With that in mind, the LT2 was design-optimized around an 87mm TB, a TB chosen for particular reasons, although there were available options for them to source a larger TB, but GM didn't.
