You know I can put my own short block together, assemble a whole running motor, build and modify with custom machining my own trans, set up my own ring and pinion etc etc, but somehow all the years I been working on cars and building motors I never learned a thing about cylinder heads and how they work.
I envy you. How did you learn how to do this. Where did it begin for you that you got to the point that you even built your own flow bench.
