i think its time to pull the head and either have a machine shop fix it or just replace it they are faily inexpensive , oversize plug wont work and if it did it would be unsafe , if you fix it right it wont give you any more problems , also try anti seize on the plug threads of the plug when replacing them next time it will let the plugs come out easier

Ok well what should i look up so i can price a new head for it? I type in head and it brings up cylinder head, head gasket, gaskets.... I dont really know what im looking for? what parts do i need to puirchase to replace this head.?

you gopt it cylinder head, and you will need a top end gasket kit also

If you're replacing the head or even taking it off to have a shop work it you'll have to replace the gaskets as you go. More than likely you'll get a whole slew of gaskets when you purchase the head gaskets and you should probably just replace all of them as you go. If you attempt to use the old gaskets you more than likely will do more damage. Also you will have to get new head bolts due to the fact that these models use torque to use bolts. If you try to reuse them you can end up with leaks and eventually destroying the motor.
