Default [Q] Updating from VRUDMI1 to 4.4 with root?

So I've been running stock rooted 4.2 for a ridiculously long time now, I've been putting off updating it, even though it seems like a pretty easy process. Now all the guides are for how to accept OTA from 4.2 to 4.3, or from 4.3 to 4.4. Any one know how to go directly from 4.2 to 4.4, or where to find a factory 4.3 image and flash with root so I can update to 4.4?
