Look at the glow plug relay, if it has a shunt, its a cali truck with bigger injectors, if it doesn't, its a noncali truck with smaller ones. Or run the vin to find out if its a cali.

They are rated 120cc but flow more like 130cc.
Another easy way to tell if its a CA truck with split shots- look at the fuel pump in the valley, if it has a black thing on the back that looks like the starship Enterprise (Star Trek) then it's a CA truck. The 96 I'm picking up has the starship enterprise and AB injectors but no shunt on the GPR.
And FYI, you don't have to pull the heads to see the injectors, just the valve covers.

Splits are not more efficient necessarily, you are wasting part of your fuel squirt for a pilot shot to decrease noise and get a little pre-burn going on to help burn the fuel from the main shot. Split shots are also oil hungry little SOB's, the AB's aren't too bad but the AD's in the Super Dutys are real bad on oil use. Which is why most people go back to singles... less oil needed for the same amount of fuel.
That you for the correction. So after reading this it seems the split injectors are a 120 or 130 cc compared to the smaller 90cc singles for these years?
This was done to decrease the noise?
When you state oil use what do you mean? The oil volume used to actuate the injectors?

That sound kind of crappy it use a lot of oil to fire the fuel will that put more stress on the high pressure oil pump or were the oil pumps in the cail truck mad just for that? I was looking on you tube an seen this vid of a guy changing the top half of the engine oil aka injector oil with the cali truck dose the oil get blacker quicker cuz it use more oil to fire each injector?

No the split shot injectors will not put more stress on the HPOP system, they just drain it faster and can make the truck fall flat on the top end if you are WOT. In my early 99 that had AB's and a 15° HPOP at WOT in my 80eco tune the truck was struggling to hold 2200 psi at 90% DC if I remember right. But that was with my foot nearly on the floor pushing 26-27psi of boost and going about 90
