Don't you have to take out the valves? Maybe, it's possible without taking out the head, I don't know.
I checked information about the Skyactiv engine. It's actually not rebuildable as the block is aluminum. You just buy a new one.

Here is a forum about problems with the Miata NC: https://forum.miata.net/vb/forumdisplay.php?f=119
230 pages of different problems.
Of course, there are fewer problems with the ND as it's still under warranty.
An expert on DI valve deposits who knows nothing about the walnut blasting procedure; interesting.
Out of those 250 pages, please cite the posts where Miata owners report having to rebuild their engines at 100k miles.
