Camshaft won’t turn over - Motor or engine problem

Hi guys. I have a problem, so I thought maybe someone could help.
So I recently bent my valves and I got them replaced with GSC standard size. After installing the valves back into the head and going to reinstall it. I had to redo timing because I jumped timing, the camshaft won’t crank or rotate. Tried to rotate it but it’s stuck hard and I don’t want to force it to possibly cause my valves to bend again.


Does anyone know why the camshaft is not turning?

Maybe it's incorrect timing :hopelessness:
