Cylinder port polish

[best]

I have put one layer pie plate alu as head gasket and thiner base gasket, leek down test passed , engine run way better thunderfast throttle response, ride it 1hour, retorque everything, still pass leekdown test !!

Tommy, don't do this without measuring. You have to be sure of your squish gap.
You want about 0.035" with 0.020" as a minimum.
