Name that injector size

[GSX93DSM]

I need some help. Just bought a Talon a couple weeks ago. The car needs motor work ###### bottom end. Anyway The plugs were fouled up and loaded with gas. The car has a gmaf and 20g. The maf box wasnt set for the proper injector size and the safc wasn't even hooked up.... The fpr was supposedly set at 50psi. My queston is he said it had 550 cc injectors. I looked for a part number and each one has an individual one. I would lik some insight if someone woul know if they are by a pic?

they should have it etched on to the actual injector somewhere, no?
