Rocker arm question on 232 ci engine

I was looking at the push rods and noticed that they don’t have holes for oil flow. Is this common in 232 ci engines? How do the valves receive oil if they are supposed to be solid?

Well Not sure what that word is ?? but the holes in the rockers are to lube the ends to cut down on ware not to oil the valves them self.. as the rockers move up and down they have a arch to them and push across the valve tip so the oil lubes that point..
OH you said push rods no holes. i think they are mounted on a shaft and the shaft oils the system push rods just need oil on the tips. holes in the push rods supply oil to the rockers shaft mounted rockers receive oil thru the shaft.
good luck

hello

? are your rockers on one long shaft that runs the length of the head. that would be a early engine built through i believe 1974. if you do then the rockers valve train is lubricated from oil coming up one of the bolt holes that holds down the rocker arm shaft. the oil then flows down the shaft and lubes through the rocker arms slinging it. when installing you have to pay attention the orientation of the shaft to make sure that you dont block the oil going to the shaft.

I figured it out... the longest bolt holding down the shaft leaves enough room for oil to flow through the shaft. There’s also an oil passage off of it. Tricky system if you don’t look close enough
