Yes I got them. They are the conical seat (if I am thinking right) and not the acorn type that has that "bulge" as you said. My McGards take even a different wrench size that OEM, which kind of sucks.
No they should not present you any issues or problems as long as they will fit in the hole in your wheel and still allow you to get a socket in there to them.
