The metal used on the spark plug (steel???) reacts to aluminum adn over time they will fuse together. I always put "never sieze" on my plugs before installing them. Same thing will happen if you bolt an aluminum hood to your factory hood brackets without some kind of means to keep the two from bonding.
If they are siezed, you are gonna need new housings

I have run across this problem many, many times on aircraft engines. The previous post about the anti-sieze is right on. It is also very important to torque the plugs properly. Relying on your hands to tighten the plugs will invariably result in overtorque.
I have used the following method to loosen frozen plugs in aircraft engines; First get the engine to operating temp. Shut down the engine and immediately freeze the spark plug by spraying it with freon or CO2 Any other method to get the plug very cold very quickly will work. This will shrink the plug enough for it to turn loose.
As for the spark plug wrench, if you have access to a lathe or a belt sander you can remove a little of the outer diameter on the socket to allow it to fit between the plug and the shoulder that surrounds it. I also have a Snap-On brand socket that was thin enough to fit without modifying it. You might try looking for a thinner walled socket.
