'05 9-3 linear conv headgasket replacement

Just took a look at a '05 9-3 linear conv that appears to be in need of a head gasket -- oil looks like gravy, exhaust seems to be coming out of the reservoir.

Is there a step by step guide to this process. I own two '99 9-3's and I would probably do this job myself if the same thing were happening on either of those cars. But, I am not sure what the differences are with the newer 9-3's.

The price is right at about a grand, but it's a grand that I can't afford to lose.

Any input would be appreciated.

Thanks

Tom
