i thought that's how it's supposed to be, but mine seem to be solid. One end has a small dimple and the other has a larger one, with no hole in them.

YOU did not state the year or size of the motor... Early Buick motors used an internal oiling system with no oil in the pushrods,,

The '69 and earlier heads had the oil come from a small passageway in the block, up to the rocker shaft/rockers. The '70 and later engines had the traditional pushrod oiling.

You can easily convert the older engines to run a modern oil thru pushrod setup. Plug off the holes in the block/heads and use the '70 & newer stuff. Alot of BBB guys like to use the earlier heads....especially if the run in a class that doesn't allow porting.
