The drilled head bolt was designed to cure this problem. You are buying on a nos Gm 235 drilled head bolt. At this same time the overflow tube on the rocker connector was pinched off putting all the oil to the shafts. If you are using 1958 or earlier rocker parts, chev supplied a plug to be put in the supply hole in the triangle spot you see in the head gasket.
Also at this time the groove inside each rocker was offset 1/4 so it did not line up with the oil supply hole in the shaft. The drilled head bolt is only needed when you are using 1958 or earlier rockers on a engine.

Up through 1958 there is a orifice restricting the oil flow to the rockers. Then the drilled head bolt is used in this bolt hole, the same hole that is in the gaskets triangle area.
Starting in 1959 they increased this orifice to the same size of the valve stem. This blocked the original oil path. This bolt is drilled with a hole.
This was done to pressurize the shaft.
