the noise came back with a vengeance, whatever the issue was... it broke my valve cover.

Front of cover? Did you replace the tensioners when you did the chain?
I did a bone head move years ago where I didn’t install the cam sprocket spacer. Oops.
It was trouble free all day including three hour round trip to the dyno, dyno time at 20 psi boost, and ran errands all afternoon.
Two miles from home and zero warning, snapped the cam sprocket in three pieces, imploded the tensioner, and sent all the shrapnel into the oil pan.. I had it all back up and running to perfection three days later and heading to the Louisville meet.
Mistakes happen.
