I will be replacing the engine on a 2001 Deville due to servere head/head gasket leakage, and I am looking for somebody who has replaced this engine several times to advise me of exactly what I need to do to make things as quick safe and easy as possible. I use and have read Mitchell instructions on how to do this, but they are kind of vague and of course dont take into account any strange or difficult fasteners. Please provide as much information that would be helpful. I dont need basics, but anything complicated or even a factory service manual with some pics (mitchell has almost none on the engine replacement section) would be nice. thanks!!

I've done this job literally hundreds of times. I assume that you have a lift and you plan to drop the powertrain out of the bottom of the car?
Yes, I do have a lift and support table, but from what I read on Mitchell, they have u remove the subframe from below then pull the engine out from the top, but it seems to make more sense for it to come out the bottom as u said..so that's pretty much why I was asking this question..let me know some details on this procedure and possible snags I may run into..thanks !
No, don't even try to pull the engine out from the top. You might get it out eventually, and you'll want to slash your wrists before you get that thing put back in from the top and aligned.It's made to come out the bottom, and it's so easy to work on that way. I got to the point where I could have the powertrain dropped out the bottom of the car in about an hour. I was the guy that was doing lots of piston and ring replacements in these a few years ago, I did several of them a week for a couple of years. I got the procedure down so well that I could have new pistons and rings in the engine in 5 hours, from driving it into the shop to driving it back out again.Other techs would ask me what my secrets were. I had no real secrets. I actually printed off the GM engine replacement procedure, put it in a hard binder, and I followed the instructions almost to the letter. Didn't even have to think about it, just went step by step. I'll put those instructions together for you and attach them here.
That's about it. You have the whole procedure exactly the way I've done it a few hundred times. Have fun with it, I actually really enjoy working on these.

wow thank you so much for your help and insight! i loved the idea of removing the master cylinder instead of the lines. Ill be really getting into this tonight and tomorrow so ill let u know if i have any other issues..thanks again!!
well it took me about 4 hours screwing around to get the assembly out. ill be transferring stuff to the new motor and putting it back in tonight. just thought id update you on my progress..thanks again, what an easy job..i thought this would be a nightmare
Excellent. Yeah, it's not as bad a job as people think, as long as you're prepared for the size of the job. Tools and equipment are everything, this job is a nightmare if you don't have a lift.
