see if they are, doubt it though as most new heads use tapered plugs vs the ones with crush washers.

If you DO have the correct plug for whatever reason for the 4.6L then yes, you can regap them

RE: spark plug question
You can pull a plug out of the Stang and compare it ot the 25. If they are both tapered and have the same thread, you can try them but those #25's prolly don't have a resistor in them which means you could get spark knock or some serious whine in the radio from the motor.
Best way to tell is stop by an autozone and have them take a look at an autolite catalog. The catalog has specifications on the plugs including resistor vs non resistor and what alternates can be used with a particular plug. (i.e. 764 can use 25, 26, 763 etc)
add: the autolite website is not very good for tech specs... [>:]

RE: spark plug question
sorry I couldn't be more definite. I worked auto parts for about 11 years. If they look the same and they are gapped the same, they will work. Just keep an ear open for those problems. You should be fine though since you are coil on plug too... (just thought of that)
As far as I know, racing generally use a non-resistor type plug while daily drivers use resistor type. too many differences in what OEM's recommend so I won't go any further on that topic.
