my 92 SHO has almost 180,000 miles. valve shims never touched. I don't hear any tapping at all. if you hear tapping, I would check them. if no tapping, I would leave them alone. of course, that's just my opinion. I'm sure there are plenty of SHO guys that insist on checking valves and they are not wrong at all.
