You want to shape that guide area like an airfoil pointing to the middle of the port. In the picture it looks like it is going to cause turbulance to the flow that will be highest in the direction of flow. It is beneficial to have a more rounded curve at the inside radius of the bend from the chamber to the pocket. It looks like you removed too much material there and caused a "step" instead of a rounded radius.
I would sugest getting a porting template set and use it to tell you what material to remove where. You can actually cause so much turbulance by removing material in the wrong areas that your ports are bigger but flow less air than they did when you started.
