.050 would be good if you have the stock ignition. With more dramatic combustion events with higher compression the gap needs to be closed a bit in order to prevent the spark from "blowing out". My MSD manual recommended .040 for use with an MSD unit and 10:1 compression.

If you have the MSD look in the book and it'll tell you what to gap the plugs at for your particular CR. If you don't have the book, the MSD book told me .040.
