Code 43 was 02 sensor right? Ethelene glycol (coolant) can coat the
02 and the readings will be inaccurate.. So yes, a head gasket leak
can kill an 02 sensor and that code might be set.

Next if 1 + 2 were ok, 3 and 4 were bad -- I'd say its probably a head
gasket or warped head. I remember a recent 94 Nissan Altima that I
put a new fuel injector in. A few weeks later it overheated and
warped the head. I did a cylinder leakage test and heard air in the
radiator on the cylinder I put the new fuel injector in. I reasoned
that forcing the cylinder to operate after being long dormant (they'd
been running on 3 cyl for a while) had taken out the head gasket, but
I was wrong. The head warped and needed to be straightened out by
..018".

I believe your dealership gave you the correct answer/estimate. Where
you decide to go with it is entirely up to you.
