I did the .040 setting and had issues with it; unfortunately, I could not recall the specifics. I had to lessen the number to have a better performance.

However, that was before I installed my SSI and adjusting my mixture. I may have to revisit this .040 gap setting.

Check MSD's site, they have a good set of instructions. I thought it was .050, but I could be wrong.

I installed a competitor's copy of the MSD 6AL, and haven't regapped the plugs, and it runs fine. (I haven't run the car all that much either)

I'll second taking Steve's advice 0.40 is the best place to start. MSD does recommend .050 but that is a generic recommendation. I run mine just under .040.

Fray you should regap the plugs to take advantage of the larger spark these units deliver.
