People, I am doing my irst Northstar head gaskets. So far so good, but the Haynes manual was a waste of money of the this issue. I found the tightening specs, but I need to get the tightening sequence. Can someone help here? I have a 94 Seville SLS which I really like and want back on the road asap, any help would be GREATLY appreciated.

Re: 4.6 Northstar
Chilton's and Haynes are useless - far too generic.
For your needs, right now, subscribe your car to www.alldatadiy.com - GM service manual as well as rate, labor, recall, warranty, Technical Service bulletins, more info than you can ever read for your particular car.
Here's the torque sequence BUT there's a very specific method of setting starting torque and then three additional passes of a certain number of degrees of bolt rotation - there is not a final torque value.
Thank you, Thank you! Now if I can ask one more question, which service manual do I need to get? I look at your link and they are showing two, Shop\Service Info and one that they are calling a supplement. I will order right away, I need my car back as soon as I get it back together now that my older caddy is acting up.
First of all, THANK ALL OF YOU!! Everyone has been a lot of help in this new journey. I have one last question before I get deeper into this Northstar, does the intake have also have a sequence as to the tightening? Haynes show the sequence for the service cover, what about the intake itself?
Thanks!, I am doing the head job while the engine is in the car. So far so good and it is coming apart fairly easy. It helps to have small hands. I hope to be done by the end of the month, I have to work and only get to do the car on weekends. I will be nice to be able to drive her again. My 85 Fleetwood has lasted me 25 years without any problems, I was hoping to get the same out of the 94, but things happen. I have to put in a heater core due to the overheating (engine found a weak spot), it looks like that job is going to be harder than the head gaskets! Many thnks to all of you.
I would not trust AllData for torque specs. They're a great reference resource but I'd go with a FSM for that type of project. I've found AllData to be wrongs about torque specs on a few different occasions.
I have found that the N* also was in the 93, I have found some used manuals for a 93 and am going to see what the differents is in the 93 and 94. So far doing the HG's in the car isn't hard at all, but of course my hands are thin and small and I am able to get to bolts most people can't. I was surprised at how easy the water pump was. The only hard part is getting the gas lines apart! And what were they thinking with the starter? LOL LOL I enjoy learning about this N*, I am a caddy man all the way and really want this N* to come out right. I have had my Fleetwood for 25 years and it has never failed to start (of course I am the only one that works on it). After the SLS is done I am doing a total restore on the 85 . I will have both car till I am gone.
Well I am updating my travels with my N*. So far I am down to taking the valve covers off, and it has been fairly easy to this point. I am not rushing it, I want this to be a good learning tool too. I have been looking things over as I am working on it, I hope to have her done by the end o this month. I will post more as I go along, again many thanks to everyone that has helped me along the way.
