Alright this is what I am doing right now/did already:
1. Changed the spark plugs 2. Changed the spark plug wires 3. Changed the valve cover gaskets 4. Changing the intake gaskets 5. Changing the head gaskets 6. Changing the distributer cap 7. Changing the oil and filter
When I was removing an exhaust manifold I broke one of the heads off the a bolt and now the exhaust manifold is stuck on there. I was told I need to remove the exhaust manifold in order to get the heads off to change the head gaskets. Now how do I get this off? I know this happened to more than 3 people so there has to be a way. My buddy just said forget about it and just change the intake gaskets. I disagree because of finding water in the oil I know the head gaskets must be changed to save this engine and as long as I bought all of these parts I might as well finish my work.
When I took out the old spark plugs they had a ton of oil on the tips as to a point where it almost looked like black sand... what does this mean? Is the engine still worth saving? Should I just change the other gaskets and oil and call it a day? What do I do about that bolt I broke the head off of?

Yeah. What you'll want to do is drill a hole in the center of the bolt, then drive one of the screw extractors into it. They are reverse threaded so they'll turn the bolt out. You may want to treat the area with something to help break the bolt loose first, tho.

yes, go get the extractor and the right drill bit for it. Take your time!!!! spray some PB Blaster on there , see if ya can get it to soak n there somhow, and drill your hole straight too

I think when you get the heads off you will have a good look at what your cylinders/pistons look like. If you spark plugs were pretty bad then expect everything else to look dirty.

One thing to look for is a ridge along the top of the cylinder. If a ridge has developed, then your cylinders are scored and should probably be bored out. If the cylinders are smooth, then you might get away with just cross-hatching the cylinders and replacing the rings. I strongly recommend replacing all the bearings and lifters, as well. You'll want to have the heads checked. The valves may need to be reseated. Engines are almost always worth saving. Even if you get one off of CraigsList, you'll probably have to do a partial rebuild. The nice thing is that rebuilding engines is quite fun.
I tore mine down to the nuts and bolts; a complete rebuild. After everything was said and done, I was only out about $1,000 or so. That included new bearings, rings, lifters, gaskets, freeze plugs, motor mounts, and water pump, turning the crank shaft, and cleaning and resurfacing the heads. You might be able to find a crate motor for about that much, but they're usually comprised of parts picked randomly out of buckets. If you've got a stock motor, you're better off using the original pistons in the original cylinders.
I hope at least some of that made sense. Let me know if you have any questions.

Well a buddy came over and turns out I missed one bolt when removing that other manifold, so we took it off and the manifold came right off. I don't know what to do about that bolt that is now headless, but we didn't see anything attached to the head so I guess it's okay now. We are changing the head gaskets in the next day or so and I'll be sure to get a good look at the pistons. Thanks for the advice everyone.

From what you're saying, just head gaskets isn't the whole problem looks like it's tired, you'd be money ahead in the long run to freshen the whole thing up, and save time and aggrevation from tearing it apart twice!..

Find someone or get some, left handed drill bits, start drilling it and try to get it to hang up, that should spin it out. I drive a Nissan truck for an everyday vehical, its got a v6 and they are bad for breaking manifold studs, thats what I have done to get them out.

This is an old racer trick but if you drill a hole centered in the bolt like discussed previously and can find a horseshoe nail ( there rectangular and get bigger from the tip to the top) you just drive it in the hole you drilled, wedge it in there real good. Then just use a pair of vise grips and turn it out. Always works for me. BB Check this out: www.youtube.com/watch?v=KGZvQoPxhNs

If there is any bolt left to grab:
Hit it (tap) with a hammer. This should loosen the threads. Grab it with a pair of vice grips. Turn it back and fourth (a little) see if it moves. If not tap it again and try. It should come loose. Spray with PB blaster (the best on the market) If it moves, slowly turn it back and fourth till you can extract it.
If it is broken off in the head:
Tool's needed, Hammer Punch Drill and bit 1/4 or 5/16 (Lowe's) Easy out for 3/8" bolt (Lowe's)
Center punch the center of the broken bolt. Use a 1/4 or 5/16" drill bit and drill it about 1 inch in. BE SURE YOU ARE IN THE CENTER OF THE BOLT AND DRILL STRAIGHT! Use 3/8" easy out to extract the remainder of the bolt. After drilling and getting it a bit hot it should come right out.
Let me know if this helps.

If there is any bolt at all sticking out of the head take a nut that just bairly fits over what is sticking out and tack weld the inside of the nut to the broken bolt,work it back and forth a couple of times then as you start to remove it spray some liquid wrench on the exposed threads and run it back in about half a turn keep doing this so the rust dosent build back up in the threads and break it again.This works great but you might need to reweld the nut a couple of times until you get enough exposed to really melt some metal. Good luck!
