Unless it is really strangely shaped, it's not likely to hit a valve. Mine
is just a spark plug shell with a headless bolt screwed into it, and it
doesn't hit anything.

Both valves are closed for most of a stroke either side of TDC on
compression; and both are open at TDC on exhaust; so that won't work.
One way is to back off the adjustment for both valves (set the lash to say
.050" for both), turn to TDC on exhaust, and check how much clearance is
left. Ideally they should be identical, but a few thousandths one way or
the other is close enough.
