I have a 1995 Chevy K2500 Pickup and Im swapping in a cummins.
The engine is 97 12V 215HP 140,000 miles
Mods done on the engine stand so far.
Head Studs and Fresh Gasket
Head Surfaced and new springs
Hamilton Street/Towing Cam
KDP Upgrade
4K Springs
15 degrees Timing
AFC Kit
Holset HX35/40 Hybrid

Will I need more Fuel ?
DV or Injectors
I dont want Smoke

you need stiffer valvesprings and i suggest 5x.012 injectors... just tune your AFC well and you will not have any smoke, you can bump your timing to 16,5° safely !

I have the Hamilton valve springs that match the cam in the fresh rebuilt
head. Where should I get these injectors for a good price.
What company. If you have a link that would be great.

SDX Injectors 5x.012 89-98

for example :D

I would stick with stock DV's for your setup.

As for injectors I agree with Angelic0 5X0.012s would fit well with your setup.
