OK - you're most of the way there as far as verifying the timing.
Normally you line up the crankshaft pulley (lowest + largest pulley) to zero first and then check the cam alignment (top gear) for being at zero. You lined up the top one first but now when you check the lower one it should be at zero, right?
Lowest pulley (lowest + largest) is the crankshaft pulley. When piston is at top with valves closed - as you confirmed with finger pressure - you want timing mark on crank pulley at zero mark. It reads against marks just behind the top of the pulley wheel - kind of under the alternator/fan belts as they head across to the passenger side.
The fixed crank pulley marks are on a small overhanging part of the lower timing belt cover, just behind the pulley. You'll see marks "20" and "10" and five index marks. I'll call them A-B-C-D-E, left to right as you see them. A is 25 degrees. B is 20 deg. and is so marked. C is 15, D is 10 (marked), and E (angled edge) is 5 degrees. Where is zero marked?? On the flat vertical timing belt cover, with an index mark and a "0", at least on my lower cover. It's hiding behind the belts but it's there. Try a flashlight. The moving pulley mark is on the rearmost of the three pulley flanges, just a small notch in the edge of the flange.
So I think now you know where to look. If you don't see the timing index notch on the pulley, feel all the way around with your finger.
So with lower index mark on zero AND pressure built in cylinder, upper timing mark should line up with its index. For a nice drawing showing the upper (and other) timing marks see about 1/3 of the way down this page:

The cam timing mark is at about 1 o'clock as you'll see on the drawing.
I hope this helps.
There is one bug to this. The timing mark on the crank pulley can move, because the pulley is a 3-piece assembly with a middle rubber ring. Known as a harmonic damper. When the rubber bond lets go the outer ring can shift from it's proper position and it no longer indicates anything of significance. Sorry, but it's true. See where it lines up and we'll go from there.
Oh yes - belt timing stripes. Those are to help line up the timing when you install the belt. One can ignore the belt marks (aftermarket belts often don't have them) and align timing entirely by the marks on gears. Using the belt marks makes it easier and faster but the marks can be ignored.
