So I got them all adjusted to .006" & .013". None looked worn so that's not an issue
235 Valves #2 I'm still hearing something, so I listened with a long screwdriver and valves #4 & #6 are louder than the others. They have a thunk sound where the others are just ticks. Any ideas of what to look at next? The push rods don't appear to be bent. Could it be the valves themselves?
