I have never seen anyone recommending overclocking, say, core 1 and 2 more than the others. I always read to sync all cores to the same speed. Any reason for this?

Depends what your motherboard and CPU support. My 6700 won't run all 4 cores stable @ 5.09GHZ, but I can run dynamic ratios and run 2 cores @ 4.99 and 2 cores @ 5.09GHz. I can't control which cores are running at what speeds at any given time, though.
You can experiment with it by setting your 1,2,3, and 4-core ratios to something like 47,46,45,44. Open up the sensor window HWinfo64 and run a simple benchmark like Geekbench and observe the the Adjusted Core Frequency values and core temps.
I haven't noticed any benefit from running split speeds other than a slight drop in max core temps. Benchmark scores drop for me. But to be honest, I haven't done a full investigation. Maybe you could experiment and share your experiences?
The best OC is to individually OC and test each core and each pair and triple etc. Then set the best possible 1,2,3,4 core OC. As you can see it's a lot of work for almost no gain to do it proper.
Usually you could run adaptive voltage and these core offsets 0,0,-1,-1 to what ever speed you want and it would give you that tiny boost for some tasks that you won't notice anyway.
I've heard fables of motherboards which allow you to set individual core speeds or at the very least disable a specific core from use.
Unfortunately I cannot do so with my current hardware. Which is sad, I'd love to disable a certain core just to see how high the other three could go.
