27 ohm stock Ford injectors?

I recently purchased a set of (6) 4.9l injectors. They are the factory Ford gray tops, which all I have seen so far ohm at ~14.4 ohms. The whole set of these ohms in around 27 ohms. I think that they will be fine on my factory ecu, due to them being high impedance, which the ecu is set up to run anyway. Why are these reading so much higher than all my other injectors would? Part number on these is E67E-B4B. I looked them up and anything I found says they should be 14.4 ohms.

12-16 ohms is the usual reading for a Ford high impedance injector. Not sure why those would read 27, but I would test them to make sure they open properly.

Hook up a hose to a pressure sprayer and energize the injector by applying a 12v current. the injector will click on and you should get a good spray. 12V won't harm the injector, but don't leave it on for very long periods to avoid overheating.

If you have a Megasquirt you can use the injector test mode to pulse the injectors.
