The "Comp Cams" Magnum roller tip rockers keep tapping. My mechanic suggests that I need 3/8" screw in studs because the high lift camshaft (.465in/.488ex) is causing the press in studs to come out. He insists that installing screw in studs will make my tapping rocker arm problem go away. Does this sound correct to you? Also please preview the video posted below and give your suggestions to whether my mechanic is adjusting the rocker arms correctly by adjusting while the car is running, or should he be using the feeler gauge/valve lash method. With these type of rocker arms is it necessary to set valve lash? Thanks a Million!
