heres one of mine. see th evalve seat where its cleanest looking, this is after lapping the valves, in your pic it looks like you skipped along the top part, so in the clear still. all i did to the chamber its self was to smooth it out. didnt remove much at all.
in this pic you can see i worked it from one end, the lip there is like 2 mm's did that all the way around all over, except where the castings needed to be ground out deeper.
ill whore this one again, cause it looks damn good to me lol its only ground down, not polished yet.
