Horrible Freight sells a pair of stethoscopes (as do a lot of other
people) that will prove useful in pinpointing the source of the
noise. It is possible that you have a bad lifter or a bad bearing.
You can remove the valve cover to narrow things still further without
throwing oil TOO far.... If you have no stethoscope, you can make
one with a long skinny bolt stuck into a rubber tube, stuck into your
ear.
You can put pressure on the drive train by having one person
feathering the clutch while the other listens (with their toes tucked
in).
