I’m not sure what you would call the shape of a cam lobe, like a acorn almost. So say the top of the accord is should be at 3 o’clock, which would yield both valves closed. If the cam is flipped 180, then the tip of the acorn shape would be pushing the lifter up, opening the valve. And if the valve is open, I’m not gunna have compression

The only way this would work like you think would be 90 out. Like it was said, the piston goes up and down, it doesn't know or care what the valve events are. As kirk clarified and I suspected, you can only install the cam one way. I would try backing off of the lifter preload if you haven't already. You can also try a few drops of oil into one cylinder and see if the numbers on that cylinder improve. You could also use a leak down tester on each cylinder and see where the air bleeds out from. Hissing throttle body? Intake valve/timing issue. Exhaust? Exhaust side. Crankcase? Bottom end. Keep that rain dance going!
