Ok, this is beginning to look like a diary. Any input is greatly appreciated.
I popped her open again tonight and sure enough #2 Exhaust is loose. It was very loose and the lock nut was still tight. I backed out the adjuster and felt the elephant foot and the top of the valve - both smooth. Put a finger on the cam lobe (some texture, but not enough groove to feel with a fingernail). The rocker moves back and forth a little on the shaft, but it will not deflect up/down like a worn out shaft or rocker. No cracks visible.
I didn't dare take the pivot out, but I adjusted the valve again about 4 times checking, rechecking, etc. Buttoned her up, started the car and it sounded perfect. I guess I'll have to blast through the national forest for a while and see if I can troubleshoot with the lead foot.
