Just so you’re aware, running a lash cap on this valve & lock scenario is playing with fire.
The bottom edge of the sides of the lash cap are not supposed to come in contact with the locks.
In order to insure that doesn’t happen you slant to have the distance from the tip of the valve to the top inner edge of the lock be greater than the inside depth of the lash cap.
There appears to be a wear mark on the locks where the lash cap was contacting them.
In that situation, the lash cap is basically trying to unseat the locks from the valve.
The lash cap should be pushing on the tip of the valve.
