David Vizard, Uncle Tony's garage, Unity motorsport. Mission impossible Dodge 302 Head porting
I can think of several things very quickly that would help people and only take 10 minutes or less to explain. Setting valves opening closing method, finding and marking damper for top dead center with the head off, making sure dial pins are installed deep enough BEFORE torquing down heads, how to pre oil a freshly built engine, checking for full throttle before heading to the track, and the list could go on forever.
