Wow. This is like the fourth thread the last few weeks. Your going to have to do the research.
But to answer your question, the motor that CSVT#49 is building is the best, so just copy that and you should be good to go. But there is a lot of reading in that thread so I'm not sure if you could handle it.
CSVT#49's build is way over the top for what most people will ever need to do. however, if you want to build an engine right, that would be the way to do it, imho.
