From which junkyard vehicle did you pull the 4 hole 14lb injectors from? Some 6 cylinder Ford from the late 90's I suppose?
Good question. I had considered starting a donor list, and so now I will. I've grabbed some from '91 - '93 2.3 Mustangs and '95/6 F-150 4.9's, although the later should be something slightly less than 14pph. Other possible donors include:

'90 - '92 Ford Probe V6 Mazda MX-6
'94 - '98 V6 Mustang

2001+ 3L Ranger injectors are 14pph but EV6, so a new wiring harness is required, but they are the later "pencil" style injectors.

Here's a thought....

If the new injectors have better atomization, then maybe you could flip the phases of the injector banks so that they fire when the valves are open?

Maybe the injectors firing against the closed valve is why the Scorpio intake manifold gets so dirty all the time.
