correct me if im wrong. |
"water drop shaped" - the word you are looking for is "cam profile". High cam is where the cam profile loop is bigger to provide more valve lift, and the cam profile curvature is smaller to provide longer time for valve lift (for more air intake or more exhaust out)
cheers!
