Cummins Springs?

I have a number of questions here about a few different types of springs.

1. what is a 4k GSK (i assume its a govner spring kit?) is this a up grade from the 366? one thread on a different site made it sound as if it involved replacing a number of different springs in the injector pump, i think it was 3 springs. what is this?

2. i have found a lot of differnt types of valve springs. some say 60lbs, some say 5000rpm, 4000rpm, and 3000rpm. ive heard that the 60lb are the ones, but what is there a difference in the 60lbs and the 3000rpm springs? will new valve springs change the perfomance of the engine under 3200rpms???

3. when i get new valve springs should i get new TITANIUM VALVE SPRING RETAINERS & HARDENED KEEPERS? ive seen this listed as a good thing to get with the HD valve springs, on the perfomance websites. PERFORMANCE PRODUCTS

thanks for you time and for reading this yall, any help is greatly apreciated.
