Originally the tuner "posts" were tight on my NS34 where they went through the wood of the headstock. I pulled them out, sanded the covered aprt of the roller lightly with 400 grit paper, and added paraffin wax to the hole as a lube upon the reinstall.
Since yours are essentially stuck, I would try using a leather pad or a wood block against the headstock, and with needle-nose pliers gently - repeat gently - prying against the most solid piece of headstock wood you can find. Worst case, take it to a Taylor certified repair tech (if feasible) and let them do the work.
