        I know this is really reaching, but seeing as how everything has been 
tried to no avail on this car, I thought I'd throw this in and see if it makes 
any sense.  I know that backpressure in the exhaust can directly affect what 
goes on in the chamber.  Is is possible that when the exhast was knocked off of 
this car that the backpressure dropped, and the mixture ran lean for awhile?  I 
f so, could the car have possibly received some small but significant amount of 
valve damage?  The damage may be enough to cause the cantankerous behavior, but 
not enough to be readily seen when the head gasket was replaced, especially if 
not being looked for.
        One other idea on the same train of thought.  If it was running lean, 
and therefore hot, could it be possible that there was some local warpage of 
the 
head that only shows up afetr being warmed up?

        Just some way-out theories.....
