That's a scary thought right there: they simply made the .990" body to suit the 235, and used the same plunger (with the oil feed hole to the pushrod) as the Gen-3 194, 230, blah. Rocker oil through the pushrod is very common, even Chrysler went to it in the later small blocks.
It's safe if the pushrod ball is a good fit in the cup, meaning you won't lose oil pressure.
