Accidentally turned one cam counter clockwise

While trying to install my timing belt the cams both shifted to the left. In my idiotic haste I took the belt off, grabbed the cam wrench and turned one cam counter clockwise half a revolution before I realized it. I’ve turned it back clockwise so the timing marks are lined up again. Did I do any damage? Thanks

 

No you're good

 

Thank you for replying so fast. I was sweating that I just bricked my truck from stupidity

 

Nope it should be non interference so there's no way you could have valve and piston contact. Realisticly even if they could touch you'd have to really force it to bend the valve.
