Currently, I'm working on a Torrington roller bearing modification of stovebolt rocker arms, with free floating pivot shafts that won't wear on only one side. Those rockers will be lubed with full pressure by an oil line tapped directly into the main oil gallery. I'll probably use a 1/4" diameter line for that little chore.
