Yes you are right 95MustangGT. The compression will be higher if you swap heads because the '99-up's have dished pistons (to lower compression) and the non-PI engines come with flatops. This isn't a problem unless you plan to add a blower later then you'll need to lower compression to safely run higher boost.
