That looks pretty decent soo far. What you really want on the exhaust side is the wall between the two valves to come to an even sharp edge at the end, and you want it to be as smooth as possible. On the intake side, you can open it up a little bit but you dont wont it to be really shiny and smooth, this will cause the fuel to pool up into dropleys and puddles rather than atomizing with the intake charge.
