Josh, there are many ways to do it, and all of them good and acceptable. I saw it done 20 years ago on one of our customers race engines, he simply tack welded them to the end of the intake flanges as an extension that basically inserted into the ports when he bolted the intake on. You could also make a thin spacer to go between the head and intake with them welded to it. Downside may be having to use longer bolts and a spacer on the header flange also, but they stay in place when you remove the intake. You can even use the short head bolt hex cutout as a bottom support and the pipe plug that fills the upper part of the head bolt hole to capture the divider also. Many ways to get there and all are pretty easy. Just pick what suits you the best.
