Does anyone know if the Springfield GI 1911 needs to be milled to install Novak sights? I've read some sights require it and some don't. What's up 1911 guys?
Yes, the GI will need to be milled to accept the Novak sights.
You can have a competent gunsmith do it or (and this would be my choice) send it to Springfield themselves and let their custom shop take care of you , they are rather quick about turn around times and price their work very competitively.
