yes, of course.
but if you're rotating the crank, and you're off by 1degree, it's possible to rotate the crank several times before the valves met the piston and feel any kind of resistance...so knowing how many times you turned the crank will allow you to return to the starting point.

If you have that issue for more than a few degrees, you need to remove the head, set the crank to TDC (different for many motors - the FIAT uses the #4 cylinder, NOT the #1), then rotate the cams (off the block) to their approximate positions before reinstalling the head.
