I have built my share. The only "advice" I have to give is... Measure everything twice. it is like the old saying measure twice cut once. Get as much information about your build as you can, ask other people who have built that motor before. Go into the fsm do not be intimidated to admit that you dont know and ask. the only stupid question is the one not asked. If you are not sure of a measurement do not move on look it up in the fsm get it right feel confident about it then move on. The worst feeling you can have is building a motor and thinking to yourself I hope that was right. There is always a right tool you cannot build a motor "well/correctly" without them. Perfect example try building a motor without a micrometer, a dial indicator, plastigauge if you must. People used to laugh because I would and still do bag and lagel every part I also have different boxes if I build the whole car; motor, engine bay, interior, rear suspension etc. choose to have a high attention to detail. I have seen many builders over the years and one thing that all of the good ones had was a high attention to detail. When you stop, stop after you tightened what ever you are working on if you have several projects that are similar, consider leaving yourself a note as to where you left off. It would suck to assume that those head studs were in more than handtight. Cleanliness, the section of tomei where they build motors is in a vacume environment conver the motor at night, use brake clean, keep your parts and materials free from foreign matter. In the end remember that time and money are both forms of currency and you only get what you pay for, or your build will only be as good as the time and money you put into it
