I pulled #4 and #5 injectors this weekend and swapped them out with some I had pulled, disassembled, and cleaned. Car has one less nail in the early AM starts.

I identified #5 as being the main offender by cracking lines when cold. I looked down in the hole and all I saw was a nub so I pulled #4 for comparsion and trying to look around. When cracking lines it always seems to have the least affect so I figure I would poke around. I was pressed for time and couldnt get an accurate seal on #4 cylinder but it was atleast in 275psi+ range. I mostly just wanted to make sure it wasnt completely hosed.

Anyways there were no balls in the prechambers, just nubs. I've looked around and it seems no one has DIY tool solution for the prechambers. Do you really have to pull the engine for them?
