A little update here:
I removed, cleaned and painted the valve cover, the air filter housing, the frame of the cooling radiator and the fan. I could not remove the fan blades from the shaft, they seem to have grown stuck together. None the less, they look really good now, better than I expected, as I've never done anything like this before.

So far in my life I have only driven and washed cars, so it'll be a steep learning curve for me. I am going to post some pics tomorrow, hopefully of some more exciting progress.
