Which reminds me, I didn't look at the A, B or C stamped on the head by the spark plug holes. There was a DIY heat shield there, a thin sheet of aluminum, being held on by the coil's bolts. Someone was concerned with heat rising up off the catalytic converter, it seems. Thought it was OE with how well it fit until I noticed the relief cuts made in it, obviously made by hand shears.
Ecky, thanks. I'll start banging on things to see what's rattling one of these days when I'm in/around those areas anyway, or when it starts bugging me enough.
