The last plug is VERY stubborn. I can turn it a total of about 3/4 turn, then
it binds up. I've sprayed PB Blaster down in the plug well (which is centered
in the valve cover) several times today. I'm going to try turning it again in
the morning.

Do I just keep trying (turning back and forth 3/4 turn) even if there is no
change in the resistance? Do I eventually use the breaker bar and force it
out? Then look into installing an insert?

Speaking of which, can inserts be done in-place? Or must the head be removed?

Thanks,

If the last plug is the same as the damaged one you removed,
you have little choice but to strong-arm the plug out. Everyone will
tell you that you should remove the head in order to properly install
the insert. I've done it in place, taking precautions to prevent the
metal chips from entering the combustion chamber. Granted, this was
on an aluminum head (similar to yours, I'm sure), and I could
literally crush and grind the chips between my fingers. Figured if
they were THAT soft and brittle, then the one or two I might have
missed wouldn't do TOO much damage.
