Thanks Roger,

The problem is that I've already pulled the distributor, AND the
drive gear, so I can't trust the drive gear position any more.

Here is what I did:   remove the valve cover on the right head.
Watch the rocker arms for cylinder #1 (the one at the front of the
car on the right head).   Turn the engine over by hand, watching the
two rocker arms move.  I notice that when the TDC mark on the pulley
is lined up with the case, you either see one of two situations:
(A) the intake valve (2nd from front) is opening and the exhaust
valve (frontmost) is closing.    (B) both valves are closed.     In
my mind, (A) should be the TDC position, right?    It's entirely
possible i'm committing a massive brain fart here.

Am I right in assuming that on a 4-stroke engine like this, the TDC
mark on the pulley turns at the speed of the crankshaft, so there are
only two possibiilties (either correct, or 180 degrees off)?
