I believe I need to do is pull the spark plug out on whatever Cylinder you’re working on, put your finger or thumb over that Cylinder and wait till the piston comes up on the compression stroke, and you’ll feel the compression blow by your thumb or your finger. Then you’ll know it’s at top dead center. However, at this point, I’m gonna back out and let the masters talk to you. I don’t want to confuse you. I wish you well.
Anyway, this is how I think.
Yeah, some master may chime in here :-)

Open your push rod tubes and hold them up with a paper clip and rubber band so you can see all the push rods. When both push rods of one cylinder are in motion, that cylinder is in overlap. At that point, both cams of the other cylinder will be on their base circles. This is where you want them to adjust the pushrods. It's really about the cams being on their base circles that's critical, not being at TDC necessarily.
That's how I adjust push rods and its worked well for me. When one cylinder is in overlap, the other one is in position for push rod adjustment. It's that simple.

As the front ones already pumped oil in the rockers, they must be filled with oil now and be more suitable for adjustment. (Just my own thought.)

Actually there is.. The HD flatheads had them.. So did the early panheads and knuckles. Pans and knucks had hydraulic pushrods.. Go figure.. In this case, no..

The head line is my fault. I mean push rods off course. Hydraulic lifters and adjustable push rods. I do not know how to correct the head line.

I do pretty much the same as Harley1004 skydude426. I rotate the rear wheel with my finger over a spark plug hole to feel the pressure and then stick a zip tie in it. Real easy to find TDC with my fingers holding the zip tie. It hits the highest point and then if you go too far just bump it back. Works every time. As for your bleed down issues or doubts you have two choices the way I see it. Either trust in yourself and fire it up, or redo them. I hate doubt. LOL!
