A tick tick tick can be a leak in an exhaust gasket or a small crack in
the manifold somewhere that only lets a blast out when the pressure is
strong enough to pass through the crack so it pulses in time with the
engine.

Maybe the manifolds need a retorque? That is pretty common on those
long heads.

Heat riser valves are bad for that tick tick tick, but I doubt you have
one although some Jeeps had them. On those the spring can get weak so
the weight on it allows a tick that can really sound like a rod bearing
thinking on going south. That is a valve below the carb with a tube
running under the carb base.

A valve in the exhaust can cause it too, you mentioned something about
an old pulse air I think and the noise comes in pulses???? Hmmm....

A collapsed valve lifter can make a tick too.

You're not hearing ping at idle. Take it to somebody that knows what they're
doing.
