You've got cam & ignition timing confused.
Back in the day, the 5s-fe had a distributor on the end of the intake camshaft. If the timing of the intake cam was off - the ignition timing was off.
Your 5s-fe is distributorless. The cam timing can be anything, but the ignition timing will not be affected. Your ignition timing can not be adjusted. There is no reason to check ignition timing in this case.

Check cam timing. Take the valve cover off & on the camshaft intermesh gears there are markings. Set the crankshaft to #1 cylinder TDC (That's 0* on the timing belt cover gauge). The alignment marks on the camshaft intermesh gears should be exactly the same.




That's the long way of saying set the crankshaft to TDC, take your 10mm valve cover bolts off & the valve cover & check the timing.
