How to change injectors??

[Maxxman23]

I have a set of new injectors for my 83' C30 and I'm hoping to install them myself and before friday 9/28. Can anyone tell my the correct procedure to install these? Do I need a special open end wrench to remove and install them? Is there anything else I should know? thanks

when i changed the injectors on my 6.2 all i needed was a 30 mm socket. but it had to be a deep socket. however that was when the engine was out of the truck and the exhaust and intake and injection lines were all removed.
