Very few people know what valve lash actually is, and why there's a specification for setting it. Everybody's got their own pet method, and writing a novel the size of War and Peace isn't going to change anyone's mind. Not all cams, even for the same engine from different manufacturers, will have the same adjustment specs. There's a very simple, totally accurate way of figuring out what the lash adjustment for a specific cam should be, but getting anyone to actually check it is as likely as finding a chicken with lips!
