For those that are interested, I sent the injectors off and received this report from Boost Lab. I am actually impressed the injectors performed so well, given their age. Plus, it is peace of mind to know they do not leak and deliver the fuel I need for my application. I should get them back in the mail next week and be able to start putting it all back together. While the car is apart, I will also start on the simplified sequential journey to simplify as much as I can.
