I had a few issues getting these on. First, their hardware is mostly junk. The nuts that they provide are flanged and crimped, and once they go on the stud once they ruin the threads. The studs seem soft, and I actually stripped one out when trying to torque to the FSM spec. So go easy...
Also, the flanged manifold to head nuts in many cases cannot actually fit on the studs due to the clearance to the manifolds. So don't throw away your stock hardware, you will be reusing it.
I had to trim the manifold flange to clear the power steering pump bracket but that was fairly painless. The casting is not perfect, there is a good amount of pitting on the cast surfaces but it's workable.
The heat shields will fit on the manifolds, but in my case would not fit with stock sized turbos. May work better with other turbos, cannot say for sure.
They do look like they will provide much more flow than the stock manifolds, but I do not have a real dyno nor butt dyno to give feedback. Hoping for the best. They do look quite pretty.
