For washing, I filled up our laundry tub and immersed parts then dried and sprayed a light oil on everything. This was the last operation after throughly cleaning the parts looking for bits of machined metal.
Also spent hours enlarging the areas around the cooling fins where the casting had not sufficiently done a good job. I opened up several areas so the cooling air could easily pass through the fins on the heads. I'll see if I can find a picture to post. Ok, just took a picture...some of the passageways were totally nonexistent. Just a thin membrane of metal remained which I opened up as much as possible. I'm referring to the area between the cylinders.
