If your are going to take the engine apart, you might as well go ahead and get a rering kit for it, they don't cost much and it will save you some trouble down the road, as far as worn bearings, look for scratches, and copper color showing through, any discoloration in the bearings will mean wear, the darker the color, the more wear, and eventually will go to copper. Rings, look for scratches and sharp edges, check the cylinders for a ring grove at the top of ring travel. I don't know much of anything about cams or intakes, as i've never had money enough to build anything but a stock engine.
