A lot of guys were getting good results by aligning the exhaust port at bottom dead center with the piston and then adjusting their head squish to 1.5 millimeters
I have 1 mm of "squish" on my bike.
Note: If anyone uses the Athena gaskets, the base gaskets are a different "color to thickness" than the stock GasGas base gaskets. Always measure your base gasket thickness when doing a top end job to make sure you get what you started with, or at least get what you expect.
