Help!?! Just took apart my 360, and found bad things!

Anytime I have a set of heads off a motor I take a drill with a wire wheel and clean all the carbon off the valves along with the combustion chambers then replace the valve guide seals. I also clean the carbon off the tops of the pistons if I am going to reuse them. I agree with longarm, if you got it apart you will be able to put it back together.

If this is your first motor I would get this book...

I have rebuilt many small blocks and I still use the check list in the back when putting them back together.
