For the port area of the valves, dump regular valve oil down the leadpipe. This has the added advantage of protecting your leadpipe against deposits.
But I have always used a light machine oil, like 3-in-1 or clock oil, for the rotor shafts, both front and rear. It lasts longer, and provides better lubrication for these higher-wear bearing surfaces. Don't forget the linkages.
