Putting new heads on for the first time

[GreenMystChevy]

I just bought some new heads for my 350 that I am putting in because it was cheaper to buy new ones than to get the old ones redone. I have never replaced the heads before and really know nothing about it.
The engine has never been rebuilt and has a lot of carbon and whatnot sitting on top of the pistons. My question is, what do I do from the very start? How do I torque it, what and how can I clean stuff, how do I put the rocker arms on, what do I need to watch out for. etc.? A step by step analysis would be nice, if that's what it takes. Thanks guys for the help. Hopefully I can get this car running so that I can drive myself to work instead of bumming rides from dad : )
