I finally got everything together to change the spark plugs in an attempt to troubleshoot my P0308/P1316 codes. Very first plug I tried to get out was for cylinder 8. And its stuck but good. I have it soaking in penetrating oil overnight but not expecting miracles. Likely the last person to change the plugs didn't use anti-seize compound or they are the original 100k miles plugs and stuck from age.
Does anyone have any ideas on how to get these plugs out without snapping them off?

One of the mechanics I use swears by soaking in coke over night, says it works every time.

 

search for mentions of the Ford TSB on spark plug removal precautions/procedure
on the modular motors.

i've posted it multiple times.

 

I got them out after soaking them in carb cleaner overnight. Some were extremely tight but came out without breaking or messing up the threads. Unfortunately the new plugs didn't fix the cyl 8 miss and the olf plugs looked fine.
Thanks everyone,

Dave
