Getting rid of the reverse taper was the first thing I went after. The only issue now is spacing between runners 2-3 after porting. I have to modify 2 velocity stacks to get them to work. I will take some pics to show the spacing problem.
Ok, I was wondering if there was even enough material at the top of the N1 runners to get a good forward taper on them or if there was only enough to make the runners straight.
So you are going to have to grind one side of both stacks and mate them closer to each other to line them up?
