Before I had the machinery, I used wire brushes or scrapers, however all of these can and will damage the seats which will then need to be recut.
YOu said your valves were pitted ? what have you done to get over this situation ??

Just seen the pic of the semi cleaned head. Those chambers have had a bit of work done on them for sure. Have you got any pics of the ports? Did the engine come with a carb or carbs? Id be whiping the gearbox off the block next. You might be in for a pleasent surprise!!
