Well guys I really think im screwed here. It's flush with the head so we tried to use a screw extractor, but it just wont come out. This thing is becoming a bitch. The hole is real close to the threads. I think if I keep messing with it that it is going to end up ruining the threads. I may just have to pull the heads. How hard is pulling the heads? Will a machine shop be able to fix all this?
Oh yea, I was noticing today that I have another bolt broke, but it was like that before I even touched the truck. It is the drivers side ALL the way against the firewall.

the only way you can really mess up is if you drilled that whole crooked and went way into the head which it doesnt sound like you did.

If you pull the heads you will be able to get them out with a easy-out. If you have the headers already off then pull the intake then the heads. Make sure you get new head bolts, the factory are TTY bolts. They are only good for one use.

My dad has been working on it for a while. There is not much bolt left and he thinks he reached the end of it. He said the threads were still good, but that freakin bolt wont come out. I started reading on pulling the heads and I dont think i can do it. I have never done anything like that, and I'm sure the dealer would rape me to have it done. Any more ideas?

the passenger side near firewall one is a bitch hopefully you have some bolt sticking out of that one. I would try drilling a very small hole and get the smallest ezout I did that with mine but had to re tap and helicoil it. Anyway tha back one near the firewall we had to take the trans and motor off the mounts and slide it a few inches forward then used a 90 angle close quarter drill to get to it from the fenderwell. Not an easy job at all. the drill wouldnt clear the ac if we didnt take everything off the mounts. My boy actuallly did most of the work I just helped with the reassembly. but it still sucked.
Good luck!
Good luck!

Ok I talked to a mechanic today. He told me that pulling the heads is way too much work for a broken bolt. He said just drill the remaining bolt out smooth and re-tap. I think I am going to try to use a reemer to straighten the bolt out because the hole is a little off center and use a drill to smooth the hole, but I am not going to go that far in just because I don't want to go through the head. Then I am going to use a shorter bolt. YOu guys think this will work? It seems like the best thing to do here, or swap a 6.0 in there

Yea I had someone mention it the other day. But any way, I just used a 5/16 drill bit and drilled the screw out along with the threads. Then I tapped it with a 3/8 tap. I made sure not to go all the way to the back of the head but anyways it looks real good. Im just gonna use a grade 8 3/8 bolt i picked from a hardware store. I'm just glad I got done with it.
By the way, I ran the stock exhaust manifold bolts through the other holes and they seem like they are gonna bottom out before they hit the header. Im just gonna throw on some lock washers to bring em back a little. I'm guessing this is how I broke the other one off.
Alright now another question. There was a previous bolt broke on the driver's side against the firewall. (A real bitch to get to). Well I had all the headers on and didn't notice it. I started it up and it didn't leak where the bolt was missing. Will it begin to leak in the future? I really don't want to touch it if it is not leaking.
