Exhaust leaks at the head can sound like loud tappets also.
I thought my engine was on it's way out because of how noisy it was. It turned out to be an exaust leak.
Check your exhaust stud nuts/bolts while your under there.
That was it. Those things loosened up pretty good after the break in! Much better now
