Engine head progress

This weekend I have made some progress with the engine head. The inlet and exhaust ports have been polished and valve seals have been pressed in. It all went quite nice together. I used some Dremel tools and polishing compound to polish the ports in the inside, with extreme care to not damage the mating surfaces for the inlet and exhaust and valve seats. On the pictures you can see the dedicated fixtures to press the valve seats and guides into the head.

The upper assembly with the camshaft carriers and little brackets has also been put together. As the top of the engine will be open, it will be possible to see any leaks or other issues inside the head. The brackets are only for the test engine as the V8 holds the cam shafts with the head covers. 

The valves were almost finished, I just had to grind the top and bottom surfaces to final dimension. So they are ready to install. The material for valves is SS AISI 316.

During the week I expect to finish the bores for the cam shafts, including the bronze split bearings installation. Also the countersunk on the valve seats.
