FWIW, the typical 24 threads per inch lash adjusting fastener equals 0.042" per full turn. A 1/4 turn after removing the lash is going to be 0.010" of preload.
and that suits the HELL outta me cause I always run lifters with them GOOD snap rings, not them little wirey things. Hell, adjustin um loose probably gives a little more bottom end. Who knows?
