Removing exhaust manifold

Anybody got a step by step procedure? I took a look today and it doesn't look hard except for the heater lines that block the bottom bolt of the manifold. I'm assuming that you take those off and get to the bolts and then put em back on later.

Also mine is pretty rusty. I plan on spraying it down with liquid wrench before I take it off, and heat them with a torch if need be? Anybody have problems with bolts breaking off in the head..thats the last thing i want to do.

Thanks.

Any particular reason why you want to take it off? It's really simple. Just remove all the bolts. On the heater lines there's a bracket that you remove to help bend those out of the way. Other than that there's nothing to it.
I'm adding an HTT 62/71/13ss and I figure its a good idea to put the 3 piece on it while im in there.
Dont worry much about the bolts in the head. Mine came off no problem. The bolts on the turbo are another story! Its an easy job and if you want to make it easier, take the center section and housing apart from the exaust housing. This will make it much lighter pulling it out of the truck!
I'm not worrying about the bolts on the turbo to the manifold.

Im gonna take the old turbo and manifold off and add the HTT and HTT 3 piece as one piece.

Should I take the old turbo off, then the manifold, or a a whole? Turbo off would make more room.
I don't know if you can install the turbo and manifold as one piece on a 2nd gen. I think there are a couple of bolts that you can't access with the turbo on. It's easy enough to just take the turbo off with the manifold on. Just hope you have a triple jointed arm to get a couple of the turbo bolts off. I know mine were rust welded on there real tight and I had a bear of a time taking them off.
I guess I'll find out when I get to workin on it. Nothing a little torch persuasion can't fix..

This is correct. I could not get one or two bolts out without taking the turbo off first -- thus would be really hard to get them in and tightened with the turbo on.

Bolts on my manifold looked like they would never come out -- they were the easiest bolts to remove in my whole rebuild.
just took mine off yesterday a cake walk if the turbo is off just a 1/2" wrench or socket
Sweet. I wish I had another free day before the weekend to get this stuff on..it's gonna kill me sittin here lookin at it.
I know what you mean my truck has been sitting dead for 2 weeks now but turbo should be in in the next couple days

I can’t get those housing bolts loose!
