now i don't know at 220-240°. it might not be as noticeable, and the front bearing isn't leaking, so i guess just keep an eye on it.
Its impossible for a crank to be too long and allow axial movement like you describe...if the crank is truly pulled all the way forward it will butt up against either the front or rear bearing locking it from coming forward...and if your collet is snug it will lock it against your front bearing and prevent it from moving back...the only way possible for it to move if its truly pushed all the way forward is if the inner races of your bearing allows movement.... You need to fix this if the crank is not all the way forward, as this kind of movement can allow your conrod to come into contact with the backplate.........There is no way the crank is too long, and even if it was you would still be able to lock it in place... If i were you I would pull the flywheel off and install while you push on the crank from the inside of the engine...if it moves then it means you have movement in the bearings, it can be nothing else.
