When you fix the problem, just a lash suggestion. Get the motor as hot as you'll run it. Rip off one cover and set 1 pair of rockers. Let the motor go stone cold, maybe overnight. Then measure that same pair. Now you can accurately cold set them all, and you'll know exactly how much it grows with heat.
Good Idea Thanks!
