recently popped the head gasket on my 1.4 8v,im gona do it before selling as im on the hunt for a cupra now.But it made me think back to a posting i seen on a mobile car forum guy with a polo same think it was a 1.4 or 1.6 8v,saying needed more power,more torque,more revs,smoother delivery etc etc.quite a few advised to hunt for an equivilent 16v head of same engine size and fit that.Can this actualy be done on these engines? they made it sound as easy as:head on,16v timing belt on,DONE! surely its not as easy as that,anyone had any experience?
