I have the vehicle listed above Sport model. it has a cracked head, thinking it was the head gasket. I pulled the head, and realized it was 3 cracks in the head itself. my question is, I have been told that blue devil sealant will pretty much fix a cracked head.is this true? would you recommend going about it this way?

Welcome to 2CarPros. As you have the head off I would just get a replacement. The mechanic in a can can work in some very specific instances, but I wouldn't trust it if I had the engine apart, especially when they are a very common engine like the 4.0. The other issue with many of the sealers like these are that they plug the heater core and radiator.
