It happens to me all the time.  Nothing wrong and EGTs normal.  Joe(B)

fired up a fresh engine with tube headers last week and the
headers went to glowing red hot and 1000 deg F in about
2 minutes at 1500 rpm.   shut it down.  unfortunately, did not
have an air/fuel meter. last time i did a tractor motor with
cast iron ex manifold, we only got to about 650 and held there.

couple days later ran across an article saying that such a condition
is caused not by a lean mixture, but more likely cam timing or
rich mixture allowing the fire to still be going hard in the header,

don't recall ever getting a TR header that hot.

any comments from the engine guys in our group about the cause of
the glowing headers and hazards to continuous operation.
