New updated seal kit part #4376219 $120, it comes with new collets.
Take the fuel connectors from injectors out , replace o-ring on those.
Take injectors out, replace oring and copper seal.
Find top dead center on cylinder you work with long zip tie. Make sure you cover oil passages in the head , you dont want drop anything in those holes! Follow cummins quickserve.

Not mentioned here is that the fueling connectors going into the block that feed fuel to each of the injectors are married to that injector once installed. The metal end of them is deformed and creates the 40,000 psi seal to the injector. When removing them, number them so that you don't mix them up, or you will be buying new ones because they will get leaky after a while if you have mixed them up.

I completely missed the 2350 part, thanks for catching my obvious oversight...
