they gaps close up not get larger as the valve seats wear.
it is a big job to change shim buckets, timming belt off cams out, injectors out, a big job, maybe do it at 120 or when the timming belt due at 150 and do it all, also water pump will prob be leaking by then and it is behind timming belt so would replace that at same time.
