RE: 24 valve cummins vs 12 valve cummins
12v to 24v was midway through 1998, 24v isb to 24v common rail was in 2003. You can build massive amounts of torque from the old 12v. Their injection pumps are a little more robust. How ever fuel mileage is lower with the 12v. The 24v's are electronic, so if you want more power, all you need is a chip. As for which is better, I have no opinion. I like the old 12v's because of no electronics. I like the new 24v's because of fuel mileage and the transmissions offered behind them.

RE: 24 valve cummins vs 12 valve cummins
89-98.4 were 12valves, 98.5-present are 24valve
there was an injector pump change in 94
head redesign and injector pump change in 98.5
injection system and a slight block redesign in 03
in 07.5 the 5.9L ISBe will be dropped all together for the 6.7L. I;m unsure of the designation of the engine right now.
