The ejector is tricky to remove (and reinstall, get a couple extra pins..and springs lol), but without Military gages that are modified to clear the ejector and extractor, they really should be removed before checking headspace.
Sounds like you are on to the issue, but I would still want my headspace to pass and I surely wouldn't test it with 556 ammo, only 223 til it passed the min 556 gage.
