Some people are running a tube off the valve covers into there headers. Is this a hp advantage?

Yes it does give more HP. Creates negative pressure in the crankcase. Will help give better ring seal and takes pressure off the bottom of the pistons. Check out C&S carbs web site. They make a neat belt driven crankcase evac system that is good for about 25hp.
