All depends on what you're looking to do, but for the most part you stick with the same EPROM set that the game was originally designed with. Meaning system 6 games stick with the Green flipper rom's, system 3's use the White flipper rom's, (system 4 games kinda vary a lot, transitional era in there).
What game are you trying to use a System 7 board in?

That should work fine, and put it at IC17, then the 2716 Game EPROM at IC20. As far as the code goes, that should give you the correct order.
Not sure about hardware compatibility though, regarding displays and such. Don't know if a system 7 board can run 6 digit displays..... don't see why it can't, just never tried it.
Just off the top of my head.... board died and all you have for a spare is a System 7?
