drivability and throttle response much improved. With my low first gear(700r) I could always be first away from stop lights except for Corvettes and Mustangs! The engine run even smoother then before, no roller rocker noise its a dream. A question for the club, I had E-3 48s from my last tune-up not the proper plugs, but ran fine. When installing the new head I saw that the plugs were full of carbon! Anyone out have good/bad experience with E-3s?
