FIRST:   Find yourself a big wooden dowel that's a snug fit in the 
tube and about a foot or so long, drive it home...   the dowel will 
allow you to rock the tube back and forth a tad to loosen it, 
whereupon the vise grips clamped onto the tube will grip it tight 
without crushing it and allow you to yank it out of the head.    It 
also gives a large screwdriver something to pry against so as to help 
convince the tube to come out.


>IIRC there is a push rod tube in the way,


There is.   The valve cover has to come off and the rockers for that 
cylinder and the pushrod guide have to be removed, then the offending 
pushrod tube.  Obviously both pushrod tubes don't have to come out, 
just the exhaust.

Do not waste time trying to get it out otherwise.  Even if you do 
manage to pry it past the pushrod tube, you won't get the replacement 
exhaust tube back in the head unless that pushrod tube is out of the way.


>but if enough stuff is removed it can be done with the engine in the car.


Yes it certainly can.   Lots easier than having to pull the engine, 
by a wide margin.     Just make sure the car is supported properly.
