1999 Dodge Ram Head Gasket

Yes, the van overheated. I first got the water pump replaced. After it was installed, I started it up and a large plume of white smoke came out of the exhause pipe. The mechanic took the wires off the spark plugs (pulling out a metal piece that was inside one of the wires) and found water on the plugs and in the area the plug goes into. He said I need head gaskets and he would buy them for me since I had to go back to work. I know I goofed, but he was a friend of a good friend. He has been ducking us both since. I would sue his sorry behind, but we were alone and I can't prove I gave him the money. I compensate by telling everyone I know that he robbed me. If the repair is less than $800, I think I can handle it. I also have to have it towed to the repair shop. The van has not started since the wires were removed even though I placed the spark plugs back in the engine block. Thanks for the info. I don't want to pay a lot for repairs as the van is old, but I need transportation.
