383 Dissasembly

Hey all, just got my 383 in the mail yesterday, and I'm excited to rebuild it. This will be the first engine I have disassembled/ rebuilt so I was looking for tips on doing it, I know an engine is a lot of parts. I know the engine ran, but I am also wondering if while it's apart if I should clean it or have it professionally cleaned by a machine shop, (it's already bored .030 over and I don't plan on boring it anymore) before I have it painted and rebuild it with new parts. Thanks for the help in advance. Any other tips/ tricks/ advice on disassembling or reassembling or having an engine machined/ cleaned are welcome.
