I really dont mean to bring this up again but I will. Is there anyone that makes a aftermarket head that has more threads for the sparkplugs? My 2000 F250 5.4 blew out a plug about 5000 miles ago and was repaired with a threaded insert and now has a burnt exhaust valve in the same cylinder. I believe it was due to the insert but who knows. I was told there is a head out there for about 400.00 but have found nothing. Thank you for your response.

 

Ford started putting more threads in the '03 heads. So if you can get the heads for an '03 or '04 heritage youll be good to go.

 

Will these heads bolt right on with the same intake? when did they go to the three valve head? thanks

 

Yes, they should bolt up to your intake.

The 3v head started in '04, but the '04 heritage still used the 2v heads.

 

I think I will have a hard time finding these heads , do you recomend a location to find these ? One other thing , how do I get this engine out ? Looks like the cab needs to be removed, if I do that there will be no need to pull it out.. 2000 F250 super duty

 

I thought Ford revised the heads in 02?

 

I would even be careful with the early 2003 heads. Rumor has it that Ford used up all the old heads before they put the new heads into place. Be sure that when you buy a new head for your engine that it has more than three or four threads in it for the spark plug.

This is a huge concern for most of us with these older 5.4 engines. I for one plan to have the plugs changed in my 1999 with 80,000 miles on it very soon. The soft aluminum heads do not seem to take well to plugs that are left in them too long - rather delicate threads it would seem.

Wish me luck although I have a very good dealer and expect things will work out just fine. Hard to imagine that changing spark plugs should be a huge source of concern, but it is.

Now, we hear that the 3valve heads in the newer design tend to weld themselves to the head. Guess we have gone from the flying plugs to the welded plugs.

Ford - when do we get a break!
