I thought the bolt ends prevented holding the big hex end of things, so that when you tried to loosen the bolt, the whole shaft just rotated, and you couldn't loosne things to get the bolt out, much less either of the conical cup pieces. Without at least getting the bolt out, how did you attach a puller?

Inhex nuts can be useful where side clearances are small (as in three of the cam carrier fasteners, the head stud barrel nuts, and various of the exhaust nuts). But they are a problem if tightening them causes the stud or bolt end to protrude too deeply into the hex part. No real options here, though.

Anyway, all's well that ends well.
