My System Specs

I looked at some aftermarket heatsinks, but I am afraid they might not fit (the MSI Z87 board has the ram really close to the CPU).
Something isn't right here. You're supposed to have great thermals at stock speeds. Who installed the CPU and the cooler? The stock cooler probably isn't installed/seated correctly. Whereabouts do you live? is the store you bought your equipment from local? If so, maybe you can take your rig in and have them seat the cooler correctly (if that is indeed the removed the plastic cover from the cooler, right?) If you bought the equipment from them, they should have no problem doing this for you.

Haswell is a disaster in terms of thermics
I wouldn't say it's a disaster, necessarily. You wouldn't be able to hit 4.2-4.4 with a stock cooler on Sandy, Ivy, or Haswell. You need a pretty decent air cooler or an AIO liquid cooler for those kinds of clocks on any modern chip.
