I had a burned exhaust valve back in November. The total loss of compression in the #2 cylinder caused very rough running at all RPM and a loss of power.
However, my problem was quite serious as the valve was missing a chunk of about 1/8 in. by 1/2 in. out of the face.
A less serious burn might not cause a total loss of compression and therefore could manifest as more of a "missing" problem than rough running.
A blown head gasket will cause similar symptoms. A compression test will help to diagnose a loss of...well...compression (a serious problem), but the only way to be absolutely sure is to remove the head and inspect eveything.
