No sideways push on the valve stem. I shimmed my rocker shafts and they still need more work. But I don't have rollers. I didn't measure but I swear the valves I put in were longer stems.
Yup. Look how close the spring is to the rocker. That's a tell tale sign the shaft needs to be relocated. I had Mike make me up a set for my closed chamber slant 6 head. Since I had 318 valves put in and they are .300" longer than the slant 6 valves, I had to relocate the rocker shaft. None of them are right in stock form. "Good enough" for most builds, but not right. Mike gets it dead on, whether you're stock or modified like what I did.
