You can use a large screwdriver or prybar. Your fulcrum is the edge of
the valve cover's lip, and the action end goes just under the
hex-shaped area on the injector. Even better is to use a medium curved
heel bar, with your fulcrum to the side of the injector and the action
end in the same spot. Either way, you need to supply some opposite
force with your (leather gloved) hand to make the injector pull
straight out. The main thing to remember is that even if you hurt
something, it's likely to be the injector insert... or your hand.
If the injectors have never been molested, chances are they'll have
some truly rock-hard, fat, rubber donut-shaped o-rings. Replace these
with the new, green Viton items.
What year head are you using, and is it CIS or CIS-E? Either way you're
going to have injector inserts that the injectors sit in, and likely
they're in rough shape, too. They're all readily available, as well as
the seals that go between them and the head. I always replace all of
this.
Finally, later CIS and all CIS-E injectors' air shroud system involves
an additional piece of metal on the tip of the injector, along with yet
another seal. '84 and early '85 CIS air-shrouded injectors do not have
this, and rely instead on the shape of the injector inset tips.
I could go on... p-mail if you want more info.
