4.9l blown head gasket
My dad bought a 1992 f150 it has 150,000 miles and wont start, the guy said the truck got hot on him. We look under the hood and the the plastic around fuel injector wiring harness and fuel injrectors clips are melted. The plastic vacuum lines where melted to but only in the middle of the motor he thinks it blown a head gasket. If the truck run hot will that cause the wiring harness and the vacuum lines to melt? should we go ahead and pull the head off and have it checkout? He also needs a new fuel injectors wiring harness what year's will fit it?

I can't see a truck over heating to the point of melting all the wiring and fuel injector clips but then again anything is possible

Could be the engine has been worked on and the exhaust heat shield was not reinstalled.
One of the red arrows points to the heat shield and the other red arrow points to the exhaust air injection tube. That tube has 6 fittings. One for each cylinder that screw into the exhaust side of the head. The pipe gets real hot so if any wires or vacuum lines are routed improperly it could melt the connectors, wires or vacumm lines.
