Nice job and thanks for the pictures! I think that even if the engine never run hot there is internal stresses in the head from when it cools after casting. I think after being bolted tight to the block and going through hundreds of heat and cool cycles the shape of the head as a whole changes ever so slightly. Maybe someone else knows, after casting is a head or engine block reheated to a certain hold temp to relieve internal stresses? In my younger days the machine shop I worked had a Van Norman head surfacer for this work, as pictured in the link. The two fixtures with the round shaft on the top had clamps that would tighten down on the side of the head. To set up the head you would run the table under the head so it would have the flat surface on each side of the cutter under the head surface. Then use feeler gauges to set it as close to flat as possible. Then you would clamp it. Then the rotary broach would pass under the head cutting the surface flat in successive passes. It also doubled as a fly wheel surfacing machine. There were fixtures to mount the fly wheel on top of the rotary bit and then the tool holder you see to the left had a bit that came down and surfaced the fly wheel. Then to the far left you would use the grinder fixture to finish the job. I realize this was a dedicated use tool, but if you did a lot of head and flywheel work it could pay for itself.

Today's Featured Article - A Brief History of Tractors in Australia - by Bob Kavanagh. After Captain Cook's exploration of the east coast in 1770 the British Government decided to establish a penal colony in Australia. The first fleet arrived in 1788 and consisted mainly of convicts who were poorly equipped and new little of farming techniques. The colony remained far from self-supporting and it was not until the early 1800's that things started to improve. Free settlers started to arrive, they followed the explorers across the mountains and where land was suitable set up farms. T
