My question is ; when Fred read the note from Gary Brotherton on what he found , why didn't he ask Gary to interpete his findings. The next reasonable question shoud have been something like this - " do these marks appear to be an attemp to gain a performance advantage or are they just the  result of someone doing a valve job and and nicking the aluminum with the cutter ? "

Some people gain knowledge over time by listening to people more knowledgeable  than them and asking questions when they  still don't understand . Some are too proud to admit they don't understand and remain ignorant forever.

This sounds like an invesigation in search of a crime, to me.
