Yes it does. I forgot about those holes in the stock rocker arms. And I believe this combined with the pushrods with the oil holes will create an oil "leak" of sorts. Because those rocker arm holes are meant to send oil to the tips of the pushrods from above. The oil is supposed to come from the rocker arm shaft and some of it flows down into the pocket around the hole, and thus lubricates the pushrod (on the engine the OP is working on.) Remembering this, I believe it would be better to use pushrods with solid ends. There is no point in sending excess oil to the heads, when that oil could be better used to lube the bottom end. All the pushrods made by Chrysler for the engines with shaft mounted rockers had no holes in the ends for a reason.
