So after changing all the sparks plugs it came to be that cylinder 3 coal pack was bad which kinda suck but it was time for a tune up. So now I noticed that I have to change my head gaskets as well saw a little bit of oil the plugs in the back.

How do you know the COP is bad?

Was the oil inside the plugs or the outside?

Bet it was on the outside and there is oil in the spark plug wells.

If so, you need to replace the seals between the cam cover and head.

BTW.... usually a blown head gasket will result in a loss of compression and / or water in the combustion chamber and exhaust system.

Yes it was in the wells were the plugs go and my mechanic said the said the same thing about replacing the gaskets. And with the plus I changed all of them and the car was still missing so I check the COPS and number 3s state didn't change when I took the connector off. So I replaced it and all is well.
