First of all, don't put USE on the command line for emerge. It is not
stored and when you do the real emerge the results will be different if
you omit the USE. If you leave it in then portage doesn't know you did
it and complains bitterly with the next emerge claiming that flags
changed. Use make.conf like it is supposed to be used, don't try
second-guess portage.

Secondly, udev and sysvinit have higher versions marked stable. Portage
should just update them but apparently is not. I suspect you have masked
them in package.mask to avoid all the recefuss about udev, meaning you
have caused your own problem.

If you are happy moving to recent udev, then let portage do it.
If not, then you are on your own and have to figure out the masking
yourself. It will involve masking every new version of software that
shows up as a blocker like udev-init-scripts and util-linux. Eventually
you will run into an unsolveable conflict, maybe we are even already there
