What do you need to take apart, the rotor pack? I had to make a special puller to get the inner hub off, make sure you mark the hub to the rotor shaft. There is very little splines, so don't f it up.
The 10mm bolts on the snout and rear gear case come off self explanitory, you dont need to drain the gear case if you do it right.
I have had bunches of them apart, you have to be real careful and make sure everything goes back the same.

Yeah, I marked the gears so they will go back correctly.
I did a google search last night on eaton blowers. I found a youtube that a Chevy engineer made showing the internals of the blower. I'm making a puller right now to get the input shaft out.
Then I can put the manifold/head combo on the flow bench and see how much it drops the head. These LS9 heads aren't very good. The port I flowed was 294 cfm, which is 23 cfm down from a typical stock LS3 (317).
Thanks for the info. It's appreciated.

I got my puller made and the hub off. Rotors slid out the back.
Bolted the manifold onto the head, and got 270.
I mis-typed in the earlier post. The stock intake port flowed 291. Manifold hurt it 21 cfm. Now am going to put the manifold on a ported intake port to see how bad it hurts flow on a ported head.
