So I FINALLY finished installing my used engine today.
I don't know its history.  It has AMC heads which I
took off and resealed because the water seal was cracking.

I started it up, and it runs fine, but occasionally it
makes a tapping sound.  It is high pitched, like if you
hit an aluminum fry pan with a wooden spoon.  It doesn't
occur regularily -- it might happen once per second at
idle, then not for a few seconds, then once or twice
again, etc.

Any ideas?  I'm hoping it's a lifter noise or backfiring
because both are easy to fix.  I have my lifters backed
off somewhat at the moment and they are very loud.

I'll see if I can make a sound recording of the engine
running and post it somewhere.

Thanks all!
