You can get a block off plate, remove the EGR, plug the vacuum lines, plug the exhaust tube and it will be fine, no codes. I'm not saying it should be removed, but it can be.
As far as the coolant lines, they can be removed too. The only downside is that it takes a lot longer for the idle air control to warm up and idle down (since there is no coolant flowing through it). If it's never cold where you are you can compensate by turning the "DON'T EVER TURN" idle air screw. If the temperature varies by season freezing to 100's you'll be chasing a consistent idle forever.
I know all of this because I have done all of this.
