Fuel injector seized

Hello all,

I'm in the process of removing fuel injectors and two came free without issue, snapped free and spun out with fingers. The other two are seizing after I turn them about 1/16 of a turn. They do not snap loose like the other two. I'm thinking either carbon deposits at the base of the injector or the aluminum was partially stripped at some point. I am being reasonably cautious to avoid stripping the head threads. Presently have penetrating oil sitting on them, have used a dentist pick to get rid of all the crud at the base.

Any ideas?

Thanks,
Matt
