Q: Overheating

While driving down the high way a pickup truck tire blew out in front of me and no where to swerve I hit the tire when getting of highway I notice my truck was overheating so I pulled over let it cool down added fluid and got it back home unfortunately the truck blew a head with a huge crack so I hired help to fix the problem pulled the heads bought a new head from auto zone and had the other resurfaced I also had bought and installed new hoses, radiator ,thermostat, water pump, heater core, temp sensor, temp switch, and new pig tails plus other engine parts like 2 knock sensors push rods rocker arms springs and vales also I bought the 95 dollar gasket kit from orileys new bolts for the heads new bolts for the exhaust manifold and for the exhaust joints anyways I hired a guy to put it all back together who did but I had to go back in and fix a few mistakes like non grounded wires one knock sensor wasn't connected now I'm having a overheating problem I can't seem to find
