In over my head (rocker geometry)

there is a really small hole in the rocker body that will squirt oil toward the cup tip.

what lift cam are you running? Ever have any issues with your setup? The reason I am asking is because I want to buy a set of the comp cams rockers as well for my pulling engine. My current setup (Crane Gold) kept breaking on me and shooting the lifter outta the bore, so I wanted to go with a cup style adjuster vs the ball adjuster.
