I think that part of that is because TF has set such a high standard in the past, that we all expect it to work right out of the box this time. Fair or not, that is the way it is. They published flow numbers that SHOULD in most peoples mind produce better numbers. That was the case with Gray's, the big block TF heads responded well to proven set ups quite well, and they expected the same from the new heads. It is only one engine build, and it will get sorted out, just not as easily as maybe some of us hoped.
