Like 1stGen said you should be fine.

If you're overtly paranoind about it just check to see if the valves on your #3 cylinder are level with all the other while in thier resting position. A bent valve will hold that valve slightly lower than the others in the valve train. It's not a very accurate way to check tho. Furthermore a compression test once your t-belt install is done should alliveate your concerns.

Also if you're having trouble getting that sproket off you can use the old timing belt and a pair of vice grips as a make shift strap wrench. Just wrap the old belt around the sproket. Take the vice grips and pinch the belt so that it makes a tight loop around the sproket. Use the vice grips as leverage against the direction you're trying to turn the bolt. HTH
