Yep, RAS made the best rocker arms for BB Mopar engines but they aren't available anymore. I have a set of those rocker arms that I've used on a bunch of different engines over the years. Killer rocker arms, probably never sell these since I wouldn't be able to replace them.

So another company sells great rocker arms and is no longer.........

They have to oil through the adjusters with pushrod oiling I say that but not all of them do that, my Jesel adjusters are hollow with no provisions to oil the valve stems or cups on the adjusters other than splash oiling from the pushrods oiling them through the center of them with pushrod oiling, there are no proviosn to oil the shafts or valve stem tips either on this paired shaft system

on my 273 iron rockers with the threaded adjuster removed I drilled a 1/8" hole horizontally thru the rocker on that side from the outside in & on thru the shaft all in a straight line clocked with the valve closed then drilled/tapped the outer hole in the rocker for a setscrew which stops high RPM oil castoff from it which is a waste & also helps lock the setscrew in place as some of em ain't tight enough (not enough interference fit on their threads)
