2000 civic LX Car threw a misfire multiple cylinders code so I decided to change the plugs and wires (recently did the head gasket, distributor thermostat ect) basically everything but the plugs and wires cuz they were in good shape. Anyway the porcelain came out but the threads are stuck in the head. 2 plugs came out fine this plug broke and another plug is also about to break. With that being said if I pull the head will it need to be machined? I had it machined when I did the head gasket at 100k this car only has 106k on it please help I'm almost willing to give out My address at this point so someone can help me and show me the ways🤣 thanks guys

 

get an easy out/bolt extractor/screw removal kit.
DO NOT GET THE HARBOR FREIGHT ONES
Next time you do plugs, dont go all crazy tightening them down, And use antisieze compound
