Wtb 318 magnum cylinder heads

Im in need of a set (preferably) of used heads for a 318 magnum. My drivers side is cracked but the passenger side is ok. Still would like to replace both. The engine is in my 98 ram 1500 sport. I would prefer replacing them with the same kind of iron ones that came out of it. So if you've got a set laying around that has no cracks and are in decent shape, let me know. Or, if you have just one that will replace my cracked one i spose thatll work too. Im in Springfield Ohio. Thanks.
