It's going to be tough to get stock height doors to close on a chopped top. Before I cut the door tops, I tack weld a brace between the door posts to maintian the door gap and alignment, then cut the door tops off, chop the top, and fit the top of the doors. Also, before I make the first cut in ANYTHING, I crossbrace and X brace the body shell so things don't move around when you start cutting. And, I have the frame bolted or otherwise fastened securely to the frame before cutting. Another method I have used to maintain the door gap when I chop is to use the correct thickness of washers in the door gap tack welded to the doors and the body shell, 2 on the front and 2 on the rear of the doors.

Excessive channeling does nothing but kill cab room. I would recomend just enough of a channel to get the bottom sill where you want it. If you need the overall cab height less then the channeling and a reasonable chop, then sectioning the car is another option....
