The '99 is a short-thread head. Any modular after around 2003 model-year is going to be just fine.
One question, you say 187K miles, with less than 20K on new plugs. Does that mean they were never done until 167K miles?
Yes. I'm a bad boy. I know better. I should have done them at 100k. Honestly, It ran perfectly fine up until then. (and fine after plug replacement). It's running fine now with the repair (knock on wood).
I have fixed a few of these, to me seems like most are 90's and I think I did a 2001. I have used the Calvan repair kit, it worked perfect. I have never had one come back after it was repaired.
I'm looking at purchasing a 2001-2003 Supercrew with a 5.4, and I keep reading a gazillion posts about spark plug blowout. I'm trying to get a grasp at how common (or uncommon) this may be.
If I need to change the poll a bit, let me know, it's my first time.
Thanks!

Probably a stupid question, and not truck related, but.....
I've got a '93 Lincoln Mark VIII with the 4.6, 32 valve.
Do these heads have the blowout problem or not?
(Gonna be changing plugs real soon. I'd like to know)
Just happened to my wife's van a few days ago. 187K miles. Less than 20K on new plugs. Thank goodness I have a close friend that's a mechanic and he had us back on the road in 2 hours (after putting in 8 hours in a shop)!
Wife say's if this van leaves her on the side of the road again, it's getting tossed and she wants a new E-series. Sorry honey, as long as they have aluminum heads, it may happen.
It happened again (not the same plug, though) !!
The days are numbered for this van of mine. This time it was the number 2 plug.

This spark stuf is old news. I have a 2002 SD 4x4 crew 167K nothihg but mobil1 runs like it should and I am not easy on her. Blew 1 plug. I blame that on me the first plug change @ 60K . Guntight torque and no antisiege. Installed a timesert and invested in a in/lb wrench and antiseige . I torque them two increments and look at the plug bores while they are out. When you take your thousands of dollar invested car or truck to be serviced a real service tech writes you up. That's it!!!! he will never see your car/truck again.Some kid straight out of tech school or still going does the work . The truth is this style of head needs the upmost attention to torque and detail to plug R/R.I have never heard any blowing a plug before a plug change. I bet 85 % of the blows were are shade tree like me !!!!! ANY ONE CAN CHANGE SPARK PLUGS!!!!! IT's not the aluminum heads,Edelbrock,trickflow,brodix,chevy,dodge,m&bens,honda,volvo,toyo,noneedtokeeptyping.

Excellent point. When I took my 2002 in to have the plugs done at my dealer I sat down with the service manager and head shop guy and insisted that their best man did the job. I also let him know that I knew "stuff" so there would be no "smoke and mirror" yes sir anything you want crap. I purposely left the truck there over night so he'd have a cool engine to work on and I told them to take as long as they needed. When I picked up the truck the service manager took me into his office and explained everything was ok and that they cleaned the plug threads used the correct torque setting (which I knew) etc.
So here's hoping you're right!
