The lifters weren't full when adjusting or you didn't stop twirling pushrod when it 1st contacted the lifter. (took up all the slack)
I used to adjust them while engine running. This keeps the lifter pumped up.
Initial install I just take up the slack between the pushrod/rocker and the lifter with lifter on base circle of cam. (then start and adjust)
But I haven't ran hydraulics in years.
