Duramax- Factory repair manual for 6.6
 

Any ideas where I can get a factory engine rebuild manual for my 6.6 Duramax? I have blown the head gasket on the right side. I was floored to see the amount of billable labor to replace them, so I am debating on whether to try to do it myself or not. I have NO diesel experience whatsoever other than general maintenance. I have all the confidence and tools to do the job, but I also know sometimes it just better to pay the pros!
Thanks in advance for your input.
