No, perf kernel is not working anymore. Hasn't for a while.
I have been able to get some stock based kernels modified for CM10.1, one of them has overclocking abilities too. As for CM10.2, right now you are out of luck, as builds for it are still so new.
Sbdags has O/C kernels that work with CROMI, but those are all stock based.
