Engine assembly tips

The order of operations should be inspect, tap, clean, assemble. The cam plug can also go on after it's off the stand. The cam bearing may just be sloppy, or it may be a passage in the block is not exactly where it should be and there are multiple holes to line up on that one. I modify the cam bearings a little just in case of that because you can't adjust it once it's in. You have to replace it if you mess one up putting it in. But it's no tthe end of the world.
