It is unknown what size shim to use when installing new valves. To get a baseline you can start with the currently installed shim and then measure your clearance. The clearance should be greater than when your old valve was installed. If there is no clearance install a thinner shim and repeat until you have a valve clearance you can measure. Once you are able to get an exact measurement of the valve clearance you will be able to determine the correct size shims to install.
