Why the 1.8? What you putting it on? Why a cam swap? This sounds interesting...
The only secret is to get a good manual from your local auto parts store. Seriously. It'll step you through everything you need to know. Make sure you pre-lube with assembly lube, or at minimum oil (I recommend assembly lube, as I think the $5 tube is cheap insurance). Have you consulted ACK's FAQ? It's usually got good stuff. I check it before every project.
