Thanks for the replies and well wishes guys.
Unfortunately I did not notice any signs before the head gasket went out. I was not driving hard or doing anything out of the ordinary, unless going to In N Out is out of the ordinary. Everything else on the motor is in good working order.
As for motor swaps I am severely limited. I wouldn't mind a 3.4L 5VZ-FE swap, but I live in Nazi California and almost any swap is met with more of a headache than it is worth.
