Good info here. I will refer to it when I put my motor in next month. Saves me trying to remember stuff I seldom do. Did you buy the pan as a kit or all those individual pieces you outlined?
I bought all the oil parts separately - don't know if milodon does a kit ?
The headers seem to be of a pretty sturdy gauge material - not sure if they are stainless.
The collector is only 2.5" however - so my workshop guy is considering trimming the base and fitting a three inch tube.
I can ask my buddy what h thinks about them for a turbo application - he has some experience having built an efi twin turbo 318 that made over 600 at the crank.
