Sounds too loud for a tappet ticking, and goes away too quickly when you rev the
engine. More like a bad cam belt tensioner bearing. Did you replace the tensioner
when you rebuilt the engine ? I have never heard an injector tick... usually you need
a stethoscope or to use a fingertip on the injector to "feel" if it is working.
There are opposing views on how to break in a new engine. Some people say you
need to be gentle on the engine for a long time, and others say load it up as soon
as it hits operating temperature. I used the Mototune USA technique, and my engine
was ready for normal driving half an hour and about 25 km after first start up.

If Lamborghini can run up their engines on a dynometer to check maximum power,
that tells me there can't be any serious downside to loading up a new engine.
