The minimum of 3.3 mm is for a reason , if you start using non standard shims the cam geometry might be out and perhaps the cam might hit the cam follower or even the shim could jump out who knows . if you get to the stage where the gap is too small with a 3.3 mm shim you need to sort out the valve seats on valve and head which are very robust to start with of course . All the valves and seats i have seen on these engines have been in pristine condition irrespective of mileage .
