That is the differance between interferance and non interferance. On an interferance motor the valve will move down and ocupy the same space that the piston does when it is at top dead center. Of course they don't hit because we all have our timing set properly and the crank moves the piston out of the way
Of course on a non-interferance motor the valves will not hit the piston no matter where you set the cam.
