All I can tell you is watch out for the heli coils in the heads for the rocker shaft stands they will pull out when using studs if you run them in till they touch bottom. The stud will pull them out when you go to torque the nut, back stud off 2 or 3 turns after it touches bottom, then torque. Don't like the helicoils, inserts are better
