All 2000 F150 5.4L's are PI.
So the my uncle who runs the local ford maintenance shop lied to me when put the heli coil or whatever you wanna call it in? Just sayin he showed me on his little telescope camera they aren't the 8 thread heads
4 threads are non PI, -4 AND 8 thread heads are PI. Only the 03 + 2V modular motor model year heads are 8 threads. Some 03's ended up with 4 thread heads. That's been pretty much confirmed by ibd and others.
Yes, your uncle, using a borescope counted 4 threads in your PI heads. Since all 5.4L's have PI heads from 1999 +.
That should help...I hope. I don't think anyone lied to you.
