I did mine, I admit I was a tad nervous at the beginning, but settled into it fairly well. My goal was to clean them up without being too aggressive.

I cleaned up both intake and exhaust ports, I then polished the exhaust ports and the chamber itself. You want to go lightly if you do the chambers as any material you remove can affect your CR. You also need a junk I and E valve if you do so to protect the seats. My heads were milled some so I wasn't too concerned.
