There is more to it than just replacing the valves. The seats will most cases need to be cut, new valve seals installed, valve guides checked and etc. The shim size will have to be determined after you have the valve work completed.

Your service manual will fully explain the procedure. This can be done on a work bench as well as on the engine. A lot of shops will include this in their fee to rebuild the head.

It would be a matter of checking clearances AFTER everything is checked/replaced and then determining the proper shim. Same way the factory does it and you would do it if you were checking and reshimming valves.
