Tom,
I've found that all the "important" tips are found in Wayne's book, which I hope you have, but he understates many of them.
For example, the biggest tip I could give for building a motor is to ABSOLUTELY use the metal strips that hold the rods up in the air as well as the chain. There is a Porsche tool number associated with these - you can buy them from Baum tools or make them as per Wayne's book.
He doesn't really mention in the book that the use of the rod / chain holders is CRITICAL to preventing leaks on the case, but it is.
I have assembled many motors; early on, I'd have a second person hold up the rods and pass the chain through the opening. Invariably, minute quantities of Loctite 574 were smudged on the case parting lines which resulted in minor but annoying leaks.
Using the chain / rod holders means mating the case surfaces is a one man job but more importantly it removes your fingers from being anywhere near the case parting surfaces and makes it so that the mating and the adhesive is perfect and leak free.
Sure, the car will run fine with leaks, but who wants leaks on a brand new build?
