im in the process of doing something similar to my intake, my question is, do those hole i see inside of the EGR runner go all the way through?
if so, i think it might just be easier for me to make a block off plate for the EGR.
im definitely not going to the extremes that you did, that thing is a work of art. my only problem with making something as nice as that is that the time and money involved could be used to make a custom manifold from scratch.
