John and his machinist could give us a post on “valve angle secrets” lol. I’m sure they would be willing to pass on 100’s of 1000’s of dollars worth of testing they have done over the years. That is info that you will never see floating around.

Yup used to call it "trade secrets" its like try to find info on rebuilding a modern transmission Like an automatic out of a 10 year old mustang. You have to buy Alldata for that and even then...there are updated hard parts and valve body mods that, if you aren't in the know the trans will just fail again.
