Who knows factory cylinder heads ?
Actually 5 rods spin, 3 of 5 rockers that have rods spinning have a little rocker side to side play. I don’t think any of the lifters are collapsing. Otherwise, I would be able to push 1 of the 5 rods down a little, at least. No rods will allow me to push them down the slightest. Cam or lifters must be worn a tad. But, as I mentioned runs great and zero valve train noise.
