When I was replacing my valve stem seals, after taking out timing chains from cam sprockets, I could rotate each camshaft freely 360 degrees with spanner. So it means that valves were opening but not hitting any pistons thus no piston was at TDC.
I belive piston 1 it's like 150 degrees BTDC when setting up timing.

Correct, as I mentioned my memory was fuzzy but the point is you can watch the valve train actuation. At 150btdc, as you keep turning past this, watch the valves on cylinder 1, they should all be closed or the intakes are just closing as the piston begins it's compression stroke. If you have the cams out of sync then the exhaust valves will actually be open/opening as the piston nears TDC as you rotate it
