The two cases with the Z serial number I'm looking at have correct placement and correct orientation for the HEVs. These are V2? I sealed Duke's just to be on the safe side, but in theory, these should work like Gen as long as there is an o-ring and this one is greased and seated properly. Not having a working HEV should not be a "big deal" since the big majority of us won't use these watches for mixed gas diving, but having a working one it's just cool That said, as long as the dorn thing doesn't fall off whilst in the middle of a presentation, we're good.
