273 rocker arm adjustment

I just looked on moparts & could not find them (& I just saw em yesterday!) a new set for $25 from Joel in edinburg Pa. yes add the banana grooves on the bottom 15 deg offset holes. I would plug the side shaft holes (they're clocked wrong) by soldering & add new ones in the side of the shaft/rocker to oil the cup and the valve (hole in rocker is already there on pushrod side & cap the large outer hole on pushrod side that is used by Ma to access this inner hole that is already there & cap the top hole (273 iron adj rockers). I get the cam on base circle & drill thru rocker/shaft at that point so there is some dwell time for the oil to shoot out.
