The head has been CNC ported for better air flow and machined for higher compression. Add stainless steel valves and light weight valve spring retainers along with a PZ22 Walbro Carb and Filter and you will see up to a 2.5 HP + gains and significant increase in torque over the stock engine. Kit includes head gasket and instructions. Part # GYR-E1121-10
*NOTE YOU WILL NEED TO USE THE LO206 ADJUSTABLE MAIN JET TO GO WITH THIS CARB*
