I just got a '49 Super A unstuck that had not run for about 15 years. I ended up having to pull the head, spray PB Blaster directly on the pistons and let sit for several days. Most likely (at least in my case) the cylinder(s) that are stuck will not allow any fluid to drain, while the unstuck cylinders will allow fluid to pass. Once I had determined the most probable stuck cylinder, after pulling the oil pan, I used a piece of wood and floor jack to apply pressure directly to the crank at the connecting rod to the stuck piston. The next morning, I applied pressure with the jack to an unstuck piston that would put opposite pressure on the stuck piston, and, with another piece of wood, began tapping on the edge of the stuck piston. After several taps, the engine broke loose. Also, don't give up hope on the interior parts.
