OOOPS!!! Ordered the wrong Demon! Change Blower carb to blow through?

Jeez take yer sweet time why don't you, Ive been waiting about 4 min already!
That is a great site, I did run across it before I bought the demon because it seemed like more effort than I was willing to put in, however I'm wondering what has already been done to the bc version of the demon that would be different from a stndrd holley or demon, or if I need to mill anything if change the floats and use the enclosure.
