Impossible to say without knowing the code stored in the engine computer.
I had the same thing happen and had a fault for secondary air flow too low. I think the vacuum line that runs to the valve was cracked in the process of moving it out of the way to remove the valve cover. It could be the same thing or something completely different.

Not too many things it can be IMO. Breather hose is the first thing to check. I would also make sure the grounding straps are tight, as well as the connections to the coils. Checking the codes would definitely point you in the right direction.

Overheating wouldn't be related to the gasket change. Check the coolant hoses and bleeder screws for leaks.

Check for leaks where the upper radiator hose is connected to the radiator. VERY COMMON failure point on these cars. Again, also check the hoses. If you're not finding anything, it probably pays to have someone pressure test the system and tell you what's going on or have them fix it. Do not drive the car if it's overheating unless you want to replace the head gasket as well. Your valve cover repair is unrelated to this problem. Good luck!

And check the bleed screw for the coolant leak. Also a common failure point.
