Well it's a little embarrassing that I was checking clearance on the wrong side of the rocker (on the push rod side, as Shaker points out). On the valve side, I can insert the feeler gauge.
I do need to confirm that I don't have hydraulic lifters, but as the title says, baby steps. Thanks guys.
I should add that the companion cylinder approach is pretty easy, because you don't have to look for any marks on the flywheel; you just watch the springs (I removed spark plugs for ease of rotation). Thanks HRL.
