I did a little homework last night and looked at various crank and stroker kits and searched through some old threads. It seems like the real benefit of a 471+ stroker comes in with a set of aluminum heads where you can keep the compression higher.

From what I've been reading,a -30cc dish is on the larger side, but shouldn't present any problems. Any advantage to splitting the difference with a 4" crank and building a 440 to keep the dish smaller? Is it a wash? I guess the compression ratio will be the same either way, just less cubes.

The amount of dish you need really isn't going to affect much of anything at these power levels. If I were choosing, since the rotating assemblies cost about the same, I'd go with at least a 4.250 setup and just tailor the compression to what ever you want with the piston design and run with it.
