spark plug gap for msd

This is direct from the MSD hotline tech.

We recommend using a good quality copper plug, stay away from the hype plugs. Use a plug 1-2 steps colder than factory recommendation. Start the gap at .035 and increase at .005 increments until yousee a nice tan/caramel color on the electrode and porcelain.

Here is a site with good information on plug selection. We are not recommending that you use this brand, the site just has excellent information.
