Valid point there Frisco!!I'd say it depends how confident you are,and how skilled as in my measly opinion the 8 valves aren't too complicated.If not,Where abouts are you from Lou?I'm sure there must be some of your friends/or members here that may live locally to point you in the direction of suitable help!? ???But as Frisco suggested def get the head checked/skimmed,as my friend did his 1.3 once,didn't check it,and had to do it all again!! P.s don't kill me,but only recently just broke an f plate lx :'( if your stuck for anything! James
