please note that you might run it then with .85mm of head clearance.... this is to much....

You should run the engine with .6mm of head clearance.

To measure your head clearance, you can do the solder test, or put the piston in TDC, unscrew the head and head button, and measure the distance from top of piston to top of liner. (remove all shims)
Also measure (again, without the shims) the depth of the head button. These 2 figures should give you the headclearance without any shims.
