The headers aren't thermally broken. In addition to the exterior foam, there will also be 7 inches of cellulose on the inside side of the header that will futher slow thermal transfer since the wall is now 10" thick. All in all, the target was to have a ~R40 wall (not including windows which are R7.3).
