If you are looking for two humbuckers, you cant go wrong with the standard, Duncan 59/JB humbuckers, with a 59 in the neck and a JB in at the bridge.
Otherwise look out for a Bare Knuckles-The Mule, Warpig and Nailbomb should all suite what you are looking for. I am not too familiar with the Dimarzio line, but the super distortions sound pretty good
