Cup Style Pushrod Adjuster Screws

Looking to swap out the ball style pushrod adjusters in my Erson roller rockers for some cup style in preparation for sorting the geometry and was looking for reviews from those that have used the PRW adjuster versions, either cup or ball 3/8-24 threads. Opinions on quality, durability, etc after use, adjustments over time. I’m assuming these are what come in the PRW rockers many are using so just wondering how they are holding up. Can get Manton, Smith etc for about $150 or PRW’s for about $90ADJUSTER SCREW KIT, VALVE LASH, 3/8"-24 x 32.20mm, Top Oiler, Cup End, Set of 16
