Help identifying injectors

[EvoStevo]

So I pulled these injectors out of a Lincoln Mark VII with a 5.0 High Output V8. I cross-referenced the part # (e6te-a3b) and they came back as 19 lb. injectors, however they don't look like most of the ones you guys have. Is it an older design?

[e30power7931]

they are 19's probably just and older design mine are exactly like that but instead of metal casing it has yellowish orange like that rest of the injector

[EvoStevo]

so are there any benefits to using the newer design?

[nando]

yes, vastly better fuel atomization.

[EvoStevo]

hm, which ones have the best atomization? What do they look like? What year did they start showing up in 5.0's?

Are these better?:

look for injectors with 4 pintle holes. they all look basically the same on the outside though.
