First off you don't need it at TDC because someone else is putting it back together and hopefully they know how to do it on their own. Second, If the upper timing chain is not on nor the head then TDC is when your #1 cylinder is at the top of the cylinder. The compression or exhaust stroke are only relative to cam timing. So no cams= no problems.
