How to remove the injectors?

How do I remove the injectors? they look stuck there.

Use some penetrating oil and some heat (not excessive) with a blow torch.  Also make sure to push your wrench toward the head instead of pulling away from the head to help prevent cracking the injector boss.

The other trick is to take three steps forward and two back... in other words, turn 'em out a quarter turn, back in an eighth of a turn, out another quarter, back an eighth, adding penetrating oil as you go (Canadian Tire now carries PB Blaster btw  )
