Good stuff and just to add for the block cleaning, Ive used a high pressure gerni throughout the block, then high pressured air and finally put it in an electric oven on very low heat (I often use my tennis club oven on weekends as the old chooks arent around) for about 10 minutes then let it cool down by itself. A water repellent I found is way cheaper from 2 dollar shops and leaves a nice film that prevents rust. On stock factory everyday engines, cam bearing suffer very little wear if any compared to crank bearings.
