I dunno about this idea. I am under the impression that golf cart batteries are designed for long depleting use and not so much for the draw of starting. It seems to me that the draw of turning the starter, with the compression on a diesel, would be hard on this type of battery. Some deep cycles are designed for both uses but I believe that golf carts batts are more for just keeping a constant and long mini-draw.
If you go with golf cart batteries, got to get much bigger / beefier ones to get the same amperage required to start the 6.0.
It would not fit in the stock battery trays, which are Group 65 sized.
So there are plus and minuses --- whether you are willing to do the work.
In my case, I am inclined to get a set of new batteries under the Motorcraft 3 year no questions asked replacement warranty first.
Then, when those batteries die.. I think of next move.
In the mean time, I am using batteries inside the vehicle for aux. power, and am presently thinking of AGMs or gel cels that are chinese made, relatively inexpensive, deep cycle batteries.
I am thinking of engineering in a "cross switch" that in a pinch, let me use the house batteries to jump start the vehicle.

Just a note about CCA ratings.
If the "box" or form factor (inside, the actual size of the plates, not the physical rubber casing) is the same size, a higher CCA rating mean spongier plates, and less resistance to deep discharge damage.
So getting the lower CCA rating often gets you a better longer life battery if you don't absolutely need the peak CCAs.
My view all along is that the glow plugs put a pretty big resistive load on the batteries, and the cycle is a hybrid cranking load (like a gas engine) and deep cycle.
So I tend to go for the batteries where I know the CCAs are not grabbed at too much of the expense of the deep cycle abilities.
If you are willing to change out for larger battery trays, nothing beats simply installing much larger batteries.
