No, uprated cams vary. Alot of Kent & Pipers selection use hydraulics. Newman only do solids now (they did do a hydraulic but it was shit and killed a few engines with swarf (mine included
)).
That said, the lifters that come with Kent are absolutely shite! When i was using their cams i used to source other lifters rather than using their supplied items. Piper ive never used so cant comment
