you dont have to get a head gasket...it would be a valve cover gasket...they are like 7 bucks or something at ur local parts store...goodluck with the paint...the best way to take the paint off is aircraft remover...let sit for 10 -15 mins then pressure wash it off...wait to dry , rub the whole thing with a brillo pad then paint....it will come out amazing... good luck and post pix when complete.
