98 Expy 5.4 Head replacement. Parts list?
I am looking for a parts list that I will need to purchase to replace the head on my 98 5.4. Spark plug hole stripped, dealer fix didn't hold, stuck replacing head. Was wondering if anybody have a parts list.
Thank you
Thank you

I am am still up in the air on that one. Not sure how much one is at a junk yard yet, reman is $700. I am worried about all the work and then put a junk yard head on it. I am leaning reman probably. Is that going to mess up the engine with one older side and one new?

I don't think it will be much difference unless the other head is really worn out. Rockauto sells heads for $700 with a $125 core refund if you return the old one, maybe you can get a similar deal from the one who quoted you for a head already. Personally, if I was doing cylinder head, I'd replace the timing as well while I had the engine open. You will have to time the engine anyway, so slapping new sprockets, tensioners, chains and guides on to it would not any extra work, and I think you can get a timing set for about 200 bucks.
Other than that, it's gaskets for everything. Timing cover, head, valve cover, intake and exhaust. New head bolts of course, and studs for the exhaust manifold as the old ones will most certainly break.
Also, inspect the other head to make sure it's not showing signs of wear, as it would suck if you do all this and then the other head goes bad after a few months..

I appreciate you help. I was thinking the timing stuf as well. Truck has 198,000 on it. Debating on pulling the engine or trying to do it in the truck. Trying to get whatever special tools are required together. Everything I have wad says this is a pain in the butt so not really looking forward to doing it at all.

It is easier doing it with the engine out of the truck, you'll have much better access to everything. But it is also possible to do it while the engine is in the truck, depends if you have the necessary equipment available to pull the engine and mount it on a engine stand or not. If you don't have those, it's more practical to do it in the truck. If you do take it out, it opens up the possibilities to inspect other things as well, and remove and clean the oil pan and lower end of the engine. After almost 200k miles, there's most likely some gunk in there..

I'd say find a set of PI heads out of a junk yard and port them yourself. Youll probably need the PI intake manifold too though, but after that just the normal gaskets that would come with replacing the heads.

Don't forget new bolts. Most probably knows that, but for those who doesn't, never reuse head bolts, always get a new set of bolts whenever you take off a cylinder head.

Some cylinder head bolts are designed for 5 uses.

I guess it depends on the design, but I'm under the impression that most heads are designed with TTY head bolts, and reusing TTY bolts is a very risky thing as they will be weakened when being torqued to yield a second time and are more likely to fail. Saving a few bucks on bolts when doing a cylinder head replacement isn't really worth it...
As it pertains to the 5.4, my Ford Factory shop manual for the 2005 says the cylinder head bolts are torque-to-yield and cannot be reused and must be discarded along with the head gasket upon removal.
