I had an exhaust valve stick open in a Cessna 150 (O-200, 4 cylinder) cruise
and it resulted in a dead miss that nothing helped. I was able to maintain
altitude at full throttle and made it to a grass field about 10 miles away
(thank you ATC for the suggested heading) - seemed like a half hour, waiting
for something to crater completely.

I've also had a stuck valve in a 150 (the same plane). The plane would not quite
maintain altitude in that situation. My conclusion from these two occasions is that
the engine actually put out more power with ignition failure on one cylinder than
with compression failure.
