I was wondering, what amp sim's and software would be best for getting a Machine Head style sound like The Blackening album?

I have tried a lot of different ones but have still not been able to get a tone as cool as this album. Is it even possible dudes?

If this thread is in the wrong place, then I will delete it, I just thought that putting it in a forum with some people who have knowledge of this sort of stuff was the best idea.
ESP Baritone Flying V with EMG 81's ->Peavey 6505

This is Rob Flynns setup for the Blackening.
Hope this helps.
