Which solid roller lifter for street use

I am running solid rollers in my Demon 440. They pressure feed the roller and also thru push rods. I’ve put about 4000 miles on them. I check them in the spring and lash stays consistent. I idle at 900rpm. They are on a lunati 60331 cam if that helps. Made by BAM. Some info.
