That's pretty ugly, but doesn't 'necessarily' mean they are bad. You can get 6 baby bottles and put each injector in and look at the flow pattern as you lift the sensor plate, with the fuel pump relay(if you have one) bypassed and the pump running. You should get an nice even fan of spray. Anything less and you need to clean or replace them.

Many P-car mechanics have a little hand-pump system where you can hook up each injector and hand-pump fuel (or techron) through them to clean them.
