4.9l Fuel injectors?

i had problems with my truck missing and so i got intake cleaned out cause of carbon build up and then while doing that i put 20# injectors from junkyard 5.0l in truck and then i was running too much fuel so ive put stock injectors back in my truck and truck ran like crap. so i suspected cyl #3. a couple days before it went i have a mechanics stethescope and heard that it was staying open longer tnat the other ones and it was probably on its last days. so i stuck 2 of the 20# injectors on cyl 3 and 6, cause 6 was my cabon fouled cyl. now i jsut want to replace all of them at once with new injectors cause i want them to last and know that they will work. if stock is 14#. https://fordsix.com/forum/viewtopic.php?f=2&t=22196

and i read some where where 17# would also work at the fuel pressure the stock #14s are running at, they are injecting the same amount of fuel a set of #17s would at a normal pressure.
and summint racing is cheaper than buying from auto store and i cant find 14# on the website. my question is,

would 15# or 17# work? ive found the lowest 15# on summit racing and now i read about 17# bing the same flow rate as 14# would the 17 work
