I'm getting old and can't remember much anymore, but some ideas:
What kind of compression readings are you getting? Chevies have trouble with anything less than about 125 lbs of wind.
If the compression readings are absolutely and totally "identical", might suspect a head gasket, as commonality on those two cylinders, as you already know, are the firing order and their physical location.
I'd ignore the "rich condition" code; just means it isn't hitting on half of the left bank.
Guess I'd probaly pull that left rocker cover and see if you're dealing with a flat cam or broken valve spring(s). Valves that aren't opening can still throw a compression reading that can mislead you.
Didn't happen to cross those two wires in the firing order, did ya? Does this one have a distributor? Wobbled out shaft?
Wobbled out guides can just drive ya nuts to find. Compression guage will usually "blink" a few times before it finally takes a reading.
