I just replaced the head gaskets and my truck has a hard time starting and when it does it runs rough.
It keeps on giving me a code of P1345, about the cam senor and the crank senor not corroalting. What does this mean? and how do I fix it.

it means that they really aren'tseeing each other when they are supposed to. Make sure you have all the wires connected to the proer sensor and havn'e t pinched a wire someplace causing the one to ground out.
