Stop in for a cup of coffee

I am not sure you will be able to see the lifter itself much less if it is spinning in the bore. Almost would need to remove the intake to actually see it or maybe with a really good bore scope. I believe the grind profile on the cam is what makes it spin. Let me check on this and will get back.
I’ve read that the cam machining is what creates rotation, and I’ve read that it’s the lifter machining. And then I’ve read where it’s a combination of both! All over the map. When I had it apart last week it looked as if I could pull the lifters without removing the manifold, putting it back may be a PITA!
:lol:
Now being able to see it with the rockers and shaft installed......valid point.
