Should I mill my edelbrock performer rpm intake?

I can tell you this. "However" you get the bolt holes to align perfectly, is how you should run it. If the bolt holes are aligned, then the ports are aligned about as good as you can hope for. On mine, I ended up using JUST the intake valley pan gasket right by itself and it lined up perfectly, so that's all it got. With a liberal coat of K&W Copper Coat of course.

Twere it me , I`d make sure the gasket /heads/intake ports are perfectly lined up ,and elongate the bolt holes , then recheck how they line up and adjust it as needed , .030 aint much to over size a hole , it would only be .015 on each side the ports are the most important !
I check every engine I `ve built for port alignment , a lot of them aint what their supposed to be to start with.
