Is 24 valve or 12 valve Cummins better?

To me the Holy Grail is an early-1998 Cummins 4×4 12-valve. The rear Quad Cab doors only started opening in 1998, but halfway through the model hear they started with the computerized 24-valve biz.

By feeding more fuel into this massively-compressed engine, it’s only natural that you can unlock more power. Though, you can still out-do the factory turbo by adding too much fuel. With the 5.9 Cummins, 50-hp or 75-hp injectors are about the maximum injector size with the factory turbo.
