8MM retainers/locks on 5/16 valves: OK or not OK?

I just noticed that these locks (with the lash cap recess) actually are slightly higher than the valve tip so these will not work either. Any suggestions on a "no lash cap recess" set that will work? 5/16 10 deg & bead lock.View attachment 1715273464
You need -.050 keepers, or change the retainer to a std. height instead of +.100.
