One way to answer the question : back off the timing by about 6 degrees
(with the vernier).  Verify with the timing light that it actually moves the
timing.  If the sound doesn't disappear or at least change noticeably, it's
something other than too-advanced ignition timing.  After the experiment,
put the timing back where it was.

Should be.  However there are lots of other mechanical problems that can be
described as a ticking sound under load.  Unfortunately, an incipient rod
knock is one of them.  Exhaust leaks at the manifold/head joint also
sometimes show up as ticking noises.
