- Right! - How many years did it take Ford to get their 2 valve head right??? Longer than it should have that's for sure, but it was done, -5 years ago, finally. Oh well, - it's good....Still.

Your the first one I've heard of. Heads were redesigned for 2004, in fact the new heads were used on some 2003 models.
You would be first on the list. The 2004 2 valve head is Fords best since 1996 lol.
Other than that, -go with a Time Sert kit.
This can't be a 2004 IMO. If so, someone really did a number on it. I know they have been redesigned without any issues like this so far. I'm pretty sure the new heads have 9 threads over 4 threads in the chambers that the older heads had.

I have a 2004 that blew a plug last week. I just repaired it with the Time-sert kit. It also is a 4.6l. This engine has had nothing but problems for me. It has had a broken valve spring that took out a head and a piston, two spark plugs have had broken insulators that caused engine misses and now a blown-out plug. The truck has 120k on it. I have 2 more payments until it is paid off and I have spent almost $6000.00 in engine repairs. My next truck will NOT be a Ford.

they made the 2v 4.6 in the new 04 trucks, and up until recently.
They did away with the 5.4 2v in 04.
These guys had bad luck-the 4.6 is rated by many publications to be an extremely reliable engine. It was in the top of one popular magazines (who's name i forget)ratings several years of its production.
