While doing this make sure not to let the porting tool hit near the oil control ring path on accident and cut into it.
It really looks great honestly, sorry I didnt reply sooner I missed this thread.

I did back cut the opening edge, I could take of a tad more but not much. The pic is angled to showthe back cut. I think that is what makes the lower are (closing edge) apear to need more taking away, although more was removed later. Believe me, I did not port these the smartest way. I totally finished one, started the other and discovered many areas that needed work only to go back and forth remove more and more. I will post the final pics... The hardest area for me is the bowl area. Trying to get a nice clean finish takes so long. Any idea's? I was using a polishing (green) round stone that took forever... Maybe 4-5 stones and 2 hours on each plate. Also the center plate is going to be fun port matching it to a RE mani. Mucho to remove.....
