Seems like a good idea. I don't know why I have not done this in the past. It wouldn't take much.. just enough to take the sharp corner off, so the o ring can be compressed by the cam tower.

I always install the shaft and o rings DRY.

Then lube through the oiling holes top and bottom. Turn motor upside down, etc.. give it all plenty of time for the oil to wick into the rocker shaft.
