How difficult is it gonna be to do this myself? I say by myself, but I really mean with someone who knows what they're doing, helping if and when I'm needed.
How much is just a new head gasket gonna be, cuz I know the majority of the price is from the labor required, and also about how long do you think it would take to do? I've been so busy with work I'm trying to figure out when I can squeeze this in...
I would rather just take it somewhere, but the guy quoted me 1500 to do it, and 1800 if the head was warped and he needed to work it or whatever, and that's hella expensive.

GET THE TOOLS OUT IT NOT HARD just keep track of every nut and bolt
do bothsides while its down my thoughts
It's a 4.7L
I'm not panicking:P, and I can change the spark plugs finally while I'm in there haha, but how much would a new head gasket be, and what if the head(s)(?) is/are warped? Is that something that we could do as well, or does that need to be done at a shop?
If the heads are warped you will need to take them to a shop to be cleaned, fluxed and trued up. Like Spartan said, take it apart and keep track of the nuts and botls. Have ziplock bags you can put the nuts and bolts in and label them. Get a peice of cardboard and push certain bolts through the cardboard in the same order you pulled them out so you know what order they go back in. Have some PB Blaster on hand as you will need it and anti-sieze compound. If you need, take pics as you tear it down to give you an idea of how it goes back together. If you need directions on how to do it all, I can try to get it all out of my AllData but that will be later today when I get home. I certainly wouldnt pay 1500-1800 for someone else to do it. Lastly, get familiar with torque sequence and specs on those head, ext manifold and intake bolts.
It all looks good to me. As for the question why it happened........I remember Ford 6.1s would block head gaskets simply because of too much cylinder pressure. Thats why the Ford guys loved the 7.3s more. Just something to keep in mind.
You really need the special powder to check for cracks. Sometimes, the crack can be so hairline that you would otherwise miss it with a magnifying glass!
I would pay someone to do this process. Any machine shop will have the proper equip.
Also, the 4.7L is an OHC engine so you'll have to know how to sync the timing from each head properly to the crankshaft. This alone is not something for beginners. Unless you mark the crank/chain position and both head/chain positions, you'll never get it right on your own.
If your head is warped but can be shaved, Cometic does make gaskets that make up the difference of what you shaved off. You cannot shave off from just one side as the compression will be diff. A thicker head gasket matched up with the amount of machining can resolve this issue.
If i were you, I would pull both heads off and have them re-done with a 5angle valve job and some polishing on the ports and have a mild set of cams installed. I'm gonna guess $1500 including cams if you have a shop do the work. Mild cams generally do not need a custom tune and you'll still pick up 20hp from the cam alone. Or if the newer version heads will bolt right up with no major mods??? That i don't know.
Ran into the Same problem last year. Blew out a rad hose overheated my engine , started getting miss fires in cyl 1,3,7 and sure enough burning coolant. Because the 4.7L has the aluminium heads and iron block the heads are probably warped pretty bad. Mine were 10x outta spec and needed new heads from Dodge which at cost were around $1300 alone. Took about 24hours total time spaced over 4 days but I also replaced the Oil pump while in there because its common to go on higher milage 4.7's. The Trucks been abused good for about 30,oookm since blowing the gaskets and runnin great still.. Your looking around $1750USD in parts for new heads , oil pump, plugs , wires , fluids and gaskets. While your in there I highly recommend Cams.. !!!

Ok guys here's an update. I've been asking around, obviously on here, and friends of friends, and I posted on craigslist for anyone in the area that could help me do the job. Today I was contacted by a guy, who is a mechanic at a used car dealership, that told me he knew how to do it and has the tools and everything and depending on how much time he has to spend at my house with me, he prob wouldn't want more than like $100. I hope he actually does know what he's doing. He seemed like a cool guy. He also said that through his work, he can probably get the parts for cheaper than I would be able to, so he is going to look it up when he has a change and let me know.
Also, a SAINT posted in my other thread, saying that if I can get to shreveport, he has an xtra set of 4.7 heads that I could HAVE...Which was really the other significant problem, as you guys as well as others, have given me the impression that the heads are prob going to need to be replaced, or at least worked on, so that is absolutely awesome.
What do you guys think?
You guys mentioned something about cams? Can someone explain this in more detail to me? I don't really know what they do, how much they would cost, or why I should replace it/them while we're in there.
Thanks for everything guys, I really appreciate it. I've been telling everyone nothing but good things about these boards and how genuine and helpful everyone here is.
Ice before you go by cams and such ,tear it down find out what happened to the motor.
This is my view,that job is big,and takes alot of time to do a 4.7 sohc 100$ is hmmmmm spooky? to have someone do it for that price.
1.get a pics of the engine ,i took 115 pics before i completely tore down my stealth, that way u know where everything is,ok
2 see if block is damaged ,cracked walls ,burnt pistons,broke rings.
if that happens its a new ball game.
be very careful at what u do and how u do it.
status report when heads are off please
Well it's we just kind of lightly talked about how much he would want to do it, and it's just extra money for the guy on the side, so I guess he just sees it as money in his pocket that he otherwise won't get, and he doesn't want to say too much to make me just say nevermind and keep looking lol.
I'm sure there are people on here who wouldn't mind helping someone out for cheap, but I know what you mean haha. I'll keep you guys updated as I find out more stuff. I can't even do it SOON anyway...I'm working non-stop and I still gotta drive out to shreveport to pick up those heads from the guy on here.
