The clicking may just be a bad battery connection or a starter problem, the only thing you need to make sure off is that the valve timing is correct, see pic below, if you have the valve timing out, you may have a valve hitting a piston and stopping the engine from rotating, so re check the timing and ensure that the engine will turn by hand, you can move the cams a little to make sure alignment is correct, the spring pressure is just a valve spring under some tension, but you do not want to be trying to turn cams more than a few degrees in any direction, they should be aligned to TDC before removal, so any movement due to spring tension is not a concern.
