Third, I did find a discussion that suggested that the right side valve cover would have a higher oil level (and thus more oil droplets in the vapor) in race cars driven by high level drivers on a counter-clockwise course. That is because the G forces would pull oil toward the outside during the mostly left hand turns. As the OP is not likely to fall into this category of user, I stand by my earlier opinion that it doesn't much matter which valve covers has the PCV connection and which has the breather.

What do you bet that if you hunt around you can find that exact same engine in something else from Ford, or a different year, that has the PCV over on the other side.
