Get a set of number stamping dies, so if anything like connecting rods and caps haven't been marked, they can be identified before, or as soon as they're removed. Rod caps are not interchangeable, and if you get a cap assembled backwards even if it's on the right rod, the engine probably won't turn. Normally, inline six rods are numbered toward the camshaft side of the engine. Stovebolt main bearings are 4 different sizes, but it's still a good idea to number them to keep from getting one of the center caps on backwards during reassembly. Measure the cylinder taper from top to bottom. A cylinder that has more than .005" of taper wear probably should be bored out for a bigger piston. At 2000 RPM, rings in a taper worn bore are flexing 32 times a second, trying to maintain a seal on the cylinder walls. Most of that flexing happens in the 1 1/2 inches at the top of the cylinder where most of the wear is. That makes for poor compression sealing and very short ring life.
