If it only happens in 5th gear it's not the head. Sometimes you can get a better idea where the noise is coming from by using a mechanics stethoscope - uses a metal rod instead of the cold round metal thing. Touch the rod to the countershaft while you have the bike securely lifted and running in 5th.
