Trick Flow heads on 5.9 Magnum block

I think my PRW SS 1.6 rockers have a hole in the adjuster that would feed oil from the push rod into or onto the body of the rocker, but I am pretty sure that is there to feed oil from the shaft to lube the adjuster and push rod tip. Not the other way around. I would want verbal or written confirmation from Comp that the Mopar shaft mounted rockers will live with pushrod oiling only. I haven't seen that in any of the literature. Can barely find the Mopar version on the website or the vendors anyway.
