Everytime you repace cams or valves, you need to recheck valve clearances. If you are lucky, you can get it all back to spec just swapping a few shims around without needing any new ones.
You need a feeler gauge to measure all gaps. You need a vernier caliper or micrometer to measure all shims.
It works out much easier doing it in inches rather than metric.
Forunately, 4A-GE shims are the same used on 7M-GE and 3S-FE and others. So a Toyota mechanic should have a selection.
