Well the ultimate goal is going to be something that one would look under the hood and go why the hell would you ever do that. Reason for the weisco/k1s is that this is going to be either single or twin turbo'd, single being the easier road but I'd like do a twin setup if I can fab a manifold the way I want it.
Current plan is to HEAVILY modify the stock manifold by essentially cleaving it in half and then doing quite a bit of metalwork with the cast iron. I might try to get in contact with this guy from slantsix and see if I can get a set of his manifolds. It would be easier/less time consuming and probably work better than chopping up a stocker.

I'm also going to be tossing the stock intake in favor of a 4 barrel hyper pak
