The rockers for Mopars with the best oiling to the pushrods are the Comp Ultra Pro Magnums, T&D, PRW steel(which are a copy of the Comp).
Those have the oil feed hole to the pushrod within the groove, and the oil is fed to the pushrod via a thru-hole in the adjuster screw itself.
Direct feed..... not splash.
But....... if there is excessive leakage around where the shafts mount...... you could still have problems.
