Mustang Boards - 94 3.8 manual problem

Hey guys i have a 1994 ford mustang 3.8 v6 manual car. Just yesterday i went to chicago to visit my family and as soon as i get to the exit white smoke comes out from behind the engine block. The car seemed overheated as i tried to turn it on and crank it multiple times it would not start at all. so i called my parents and had the car towed later that night i tried cranking it again and the car turned on but failed to idle as the engine seemed like it was going to shut off unless i tapped the gas pedal a little bit. the car once again was smoking from the engine and exhaust white smoke coming out the vents inside as well .

the next morning it turned on and i drove it around the block a few times . and the car seemed to have trouble trying to idle on neutral also i kept hearing this slight ticking sound as i was switching gears can anyone please help me and. share views on what the problem might be some people said i have blown headgaskets other mechanic said might be bad radiator please help
