1 if you have the f250 with the auto lights your sensor can be broken or shorted out.
2 if you have the regular light switch you have a short in your wiring which creates a loop through your lights. Moste likely near the fuse box. the terminal will get power there from a short.
Take fuse panel out and look for the short in there. those are the only things it can be

Are you sure you got the timing correct with both heads and the crank shaft, when you installed the timing belt? If wrong, this can cause a no crank/no start situation. As far as the battery and check engine light staying on when key is off, sounds like ignition switch is malfunctioning, or computer. Why did you replace the head gaskets?

I have a 2002 Volvo v70, 2.4t . The signal light on the right side stay on at all the time

I would think it is a short in the turn signal switch but I wonder how it is getting power with the key switch off.
I would unplug the switch and see if the lights go off. Could also be a short in the hazard switch.

Ford is notorious with this problem. Even the Lincolns have it. The relay for the interior lamps is at fault. You can replace it or simply unplug it. If unplugged you will have no interior laghts working an longer. I suggest to replace the relay

Still has power to interior

Sounds like a bad ignition switch, usually in the steering column under the plastic, it should be only around $40. try AutoZone if it doesn't hellp they're good about returns
