hi removing the heads [ which is easy,] and soaking with KB BLASTER, I have tapped on the top of pistons with a piece of hard wood cut to size of the piston, and tap on the top of wood, if it clicks that piston is not seized, if it is solid that is the one could possibly stuck I have done this on a few flatheads, if you remove the oil pan, you can loosen the connectiong rods, maybe back off a 1/8 inch, this gives the piston a place to go, and you are only doing one piston at a time, if you do not back off the rods you are trying to make one piston go down and at the same time making all the others move, doing on at a time, should work once you have the engine free, now you can remove the all the pistons and with a little luck hone the cylinder and replace the rings Hope this helps, 37Ragtopman, I would rebuild the 12 cylinger Lincoln engine, if it was mine, there is nothing wrong with it, it worked back then and will work now, and it save a LOT OF MODIFYING the REST OF THE CAR, transmisson, rear end, electrical system cooling system,exhaust system suspension, front and rear, and MORE, this is just the tip of the ice berg. once you have the engine free, now you can remove the all the pistons and with a little luck hone the cylinder and replace the rings
