79cc/99cc Cylinder Head, Ported & Milled (core required) Porting & Milling:Porting / Mill .065" (Check Clearances) so block decking is notYou are purchasing machine work for your cylinder head which needs to be sent to us. The factory castings have rough edges from the machining process which limits the cylinder heads power potential. We port the cylinder heads to increase performance. We also mill these cylinder heads to increase compression. The added compression will improve your engines torque and overall power. See our article on performing this modification on our test engine.
