IMHO, since a PCV is a controlled weighted orifice that you will make things worse using two. If one isn't creating negative pressure in the crank case and the oil is getting dirty fast, I'd do a leak down to see if the rings are failing. As above, PCV on the right and restricted vent on the left has always been sufficient. E85 dies not have that much alky in it - it's not anywhere near like running Methanol. In any event, you can also reduce issues by not running the motor unless you run it long enough to get it to full operating temp. The methanol racers don't start their cars unless they can let them run up to full temp. Running cold and fat on alcohol is where the gunk comes from.
