Hey there mate, it's not the head that needs to be changed.. you want to change the cylinder and piston. You can't use the lifan 140cc because the cylinder is taller on that engine (which will cause compression and timing problems) and the pin is also 15mm not 14mm like your engine..you CAN get a 57mm big bore kit from TBolt USA - Pitster Pro, MX, ATV, Fiddies, Engines or Akunar Motorcycle Parts & Accessories Thailand which will bring your bike to 141cc..thanks!
