Yes, looked a bit hogged out. For 8k I can see why though I do think dropping the port floor is the wrong way 'round. I can see your taper but I can also see a sharp increase in area from so much bowl blending.. you'll get some flow separation at lower rpms. Remember a banana port will always flow more..
