I see this as just looking for an argument LOL I don't bring any tools to the track except for my tune-up tools. That's why I do things in a foolproof way. Double-checking everything as I go along. Like I said enjoying the process that's what I bought the car for. Of course after following the chart for all these years I know how to adjust a single valve or something like that knowing when an intake is open the exhaust is closed or the opposite in a pinch at a track if something broke. What we're getting at here is a newbie who has to start somewhere. And a good solid chart to read is a good suggestion. It's not the only suggestion by a long shot...
