Default Mazdaspeed head tapping/knocking

I’m new to this not sure if this the right place to post.
hopefully someone can help me.

did my timing & vvt on my MS6 and that I’m all done everything back together I hear a tapping/knocking from head not block.
car started right up with no problem, idles perfect and throttle response is fine.
what could it be?

Continuous tapping? or did it go away after a few seconds?
