D24T Injectors in D24 NA
Is there any benefit (HP, MPG, etc...) to adding D24T injectors into a D24 NA?
Specifically, a D24 that has a thin MLS HG and a larger bore. |

I can't think of any. IIRC, the "T" injectors are set to a higher POP, not sure if the nozzles are any different. Remember, it is the IP that sends the measured fuel spurt to the injector, so a different injector can't really inject any more fuel into a combustion chamber than what it receives from the IP.
Of more importance is that the injectors are:

Is it worth replacing/rebuilding the injectors during an engine rebuild?
Mine appear to work just fine (using small bench pump tester), but all the sprays look the same too me, lol. I keep seeing Monark nozzles in my research, are they any better than what's in the original injectors? |

Worth replacing only if they are worn or malfunctioning.
Spray pattern should look like a fox tail straight out, not a pee stream or crooked. I did use Monark GTD style several years ago. It ran fine, hard to tell if there was any performance or economy improvement. Minimal, if any. Had more to do with my careful lapping/testing/setting procedures that they were well balanced. That was years ago, no telling where the Monarks are manufactured now, or what their quality is.

I'll have to look more closely at the spray patterns.
If I do need to replace one of the injectors, is "NA10X" the correct part number? |

What is that number from? Greenbook shows 068 130 205 B, stamped near the middle of the injector body, just above the housing parting threads. Nozzle P/Ns vary, depending on T or N/A, also on markets.
