I had a something like that happen to me on a 280 z with weber carbs.
I was re jetting the carbs (basically 1 carb per cylinder) I put the
wrong set of jets in one carb so one cylinder was off. I forget if it
was rich or lean but I remember that the header for that cylinder was
glowing red hot. It freaked me out thinking if my header is red hot
what is my ex. valve looking like so I shut down the engine and
checked the last thing I was doing and found the wrong jet, changed it
and started the engine up again with no problems. I'm shure I could of
bunt a valve if I kept it running for a while.

Is your engine missing ? might have a down cylinder sending unburnt
gas into the exhaust. their are lots of causes for this from ignition
to injectors to a cracked head or head gaskets ("condensation which
tasted like water from exhaust manifold") or even a burnt valve
