How does a W2 head oil the rockers/valve train?

The newer w2 heads come both ways and if they do not come with oil hole you can drill them. Oil through the push rod is best.

My new motor has the newer head with the oil through the head. I am installing the engine now. I also have a set of w2 heads that oil through the push rod.

remember no chrome shafts with Norris rockers, you have to use the banana groove shaft and make sure the groove is on the bottom
