In my experience, a P0420 rarely lies: you have cat problems. Were you here in Texas, you could have slid like me on doing the cat for like...three years
I am really hoping I can clear the CAT before smog this summer. I might do the acid wash again on the CAT, but I did the o2 sensors so I could eliminate a variable. If P0420 comes back, I can be quite certainthe CAT is the culprit and that the head gasket problem fouled it. We'll see soon. Smog test due by August.

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
