Yeah, someone who has done it on your board and has documented the process and results would be handy. As a rule of thumb though, you can just raise the multiplier on standard / auto voltages to the point where you start hitting instability then raise the core voltage a bit at a time until it regains stability. I'm sure you know all this stuff anyway though.
I ran my 2600k at 4.14 on auto everything and it was completely stable (z68 board). More than they caused it to loop out a few times on booting and while it would take a higher clock with more voltage, I was perfectly happy with a 700MHz boost. I also ran the bus at 104 up from 100. Depending on your board you might need to manually raise the core voltage manually as you increase the CPU multiplier though if it hasn't been designed to be auto overclocking friendly.
Running a 1070 with your 2600k means you'll see a lot of improvement clocking up your CPU.
