Bare EQ Magnum heads vs. machining stock Magnums?

Ok just talked to my machine shop, they haven't started on my heads yet so I'm gonna go with the EQs.

@RAMM they really flow that much? If so that definitely seems worth it for an extra 40-some cfm. Give me more reasons to be happy with my purchase, I want to feel good about dropping $1k-plus on just heads when the whole build is barely double that lol
