The honest truth of it is that the closest I ever got to an auto shop class was sitting behind the one at my high school a couple or three times a day to smoke pot. At least, I don't remember ever entering the place. Certainly never on purpose. I'm not really a big fan of classrooms. There's just entirely too much BS in those places. All you get there is performance art and the puppets get mad if you swat at their strings. The books are much better than the plays.

So I decided to stop getting institutionalized just to get educated long before the system thought I should be trusted to make decisions of that gravity. I'm sure one of us was right but I'm not formally educated enough to correctly make such distinctions unaided.

High ratio rockers intake only

ANY Cam with more duration than stock will hurt your off the line grunt
And too much lift requires piston mods bvvc
