I figured it out. A regular box end fits on the star bolt, and the set screw adjusts the lash. The exhaust valve nearest my head had about 10 thousandths more lash than the rest. I set it to a loose 18 like the rest.
.018-.022 would be within reason depending upon cam and set at hot or cold. Those are shaft mounted rockers, likely Jessel or T&D. -Good stuff. Generally accepted to be more robust than stud/pedestal monted rockers.

Think you need to re-measure. Though I dont know your build that is not a realistic lift in a 351c or any street driven mouse motor. Not sure I'd be paying any attention but given you ran a 12.4 quarter and your car ran an 11.5, questions must be answered!!
Best,
